We have got a recent submission of the project by students of Mai Bhago polytechnic college, Amritsar, Punjab. As simple as it sounds, This project is an 8051 based DTMF controlled robot. 8051 receives decoded DTMF tones from MT8870 DTMF decoder. The DTMF input is fed from a GSM phone. There are two motors on the robot which are controlled via dual H-Bridge motor driver L293D.

If you are just starting to learn microcontrollers then this is the project you should start with. It will help you understand the basic IO control in microcontrollers using embedded C.

DTMF controls are as follows:

On pressing '2' robot moved forward
On pressing '8' robot moved backward
On pressing '4' robot moved left
On pressing '6' robot moved right
On pressing '5' robot moved stop


The download package includes source code, hex file, schematics and a description document.

Electronic Voting machine with Managed Control Unit (Project Report Included) http://www.8051projects.net/download.php?view.205 Electronic Voting Machine with Managed Control Unit
Introduction:
EVM is capable of saving considerable printing stationery and transport of large volumes of electoral material. It is easy to transport, store, and maintain. It completely rules out the chance of invalid votes. Its use results in reduction of polling time, resulting in fewer problems in electoral preparations, law and order, candidates' expenditure, etc. and easy and accurate counting without any mischief at the counting centre. It is also eco friendly.

Our EVM consists mainly of two units - (a) Control Unit (CU) and (b) Ballot Unit (BU) with cable for connecting it with Control unit. Both the units consists of one microcontroller (8052) each. The CU consists of one LCD, one hex keypad and a couple of switches, while BU consists of a candidate panel, a votecast panel and a buzzer, etc.

This project is based on assembly language programming. The software platform used in this project are Keil uVision3 and SPIPGM37.

Important Information:
Please Read this carefully as explained to me by author

i forgot to mention one thing missing in report n coding as well.
actually, in main function of control unit program as soon as controller
enters in it check the value of variable named "status" that resides in
EEPROM. If status is 1 then voting start else no voting.

if the EEPROM is new or fresh, status will have some garbage value
or 0xFF. which can be a problem on first startup.

So a small program is written to clear that status byte.

After you finish making the hardware. You have to do the following things:

1. Load cufirst.hex file in your controller.
2. Run your circuit.
3. Wait for 2-3 seconds.
4. Load voting.hex which is the real control unit program.
5. Run it.

Metro Train Prototype Project with Project Report http://www.8051projects.net/download.php?view.250 Metro Train Prototype Project with Project Report



Metro Train is one of the biggest transportation medium in Delhi connecting all ends of Delhi together. This project is a very simple train prototype of current Metro Train. This prototype is powered with 8-bit 8051 microcontroller. As you know Metro trains run in one direction at a time, so prototype uses only one motor to move the forward. There is an additional motor which is used to open and close the doors of train.

Working Of Metro Train:

When the power is turned on a message ("welcome to Bhopal metro") is displayed on LCD. Then a message "Current station is Indrapuri" is displayed and door is opened. A buzzer is also turned on when door opens. After some delay the door is closed and car is started to move forward. A message "current station is Indrapuri" is displayed also on LCD. After some time a message indicating the next station is displayed "next station is M P Nagar". After some time the train stops and a message "current station is M P Nagar" is displayed. This process is continued for five stations. In the end a message "End of line" is displayed on LCD. This whole process is repeated until we turned off the power supply.

A big thanks to Gaurav Sharma for submitting this project.

GSM Notice Board http://www.8051projects.net/download.php?view.248 GSM Notice Board




This project is a simple GSM Based project where 20x4 LCD is used as display for Notice board and GSM modem is used for receiving and sending SMS. When a user wants to display a notice/message on the notice board, user will send sms from a verified mobile number and sms recevied is displayed on LCD. Project involves simple security feature where SMS sender's number is compared with a pre-configured number (hardcoded in source code). If sms is recevied from an unknown sender, a notification SMS is sent to pre-configured number notifying an invalid access to board.

This project is fairly simple but its main purpose is to demonstrates reading and sending SMS using GSM Modem. There are many users on forum who struggles getting SMS read working in their projects. So For them this project is a starting point.

I want to thank Kiran Gowle (kirangowle) for submitting this project. I am sure his contribution will help many others on this website. If you have any queries regarding this project, Please feel free to post in forum.

Android Controlled Robot using 8051 Microcontroller http://www.8051projects.net/download.php?view.247 Android controlled robot using 8051 and bluetooth



Our robot expert Gaurav Khadasane has come up with another innovative way to control a robot. He is controlling his robot from an android phone (with a Android GUI application) over bluetooth. Project uses our favourite 8051 microcontroller and HC-05 bluetooth module.

In this project 8051 and bluetooth module are communicating over uart @9600bps. Bluetooth module HC-05 is controlled via simple AT commands. This module comes in SMD package and works on 3.3v power supply. The BT module is a SPP supported profile so it can be connected easily to any controller or embedded device. In this profile the data sent and receive to module directly comes on the RX pin of microcontroller. It becomes really easy to make your device bluetooth compatible.

L293D H-Bridge motor driver are used to control two DC motors. A readymade compact size chassis is used to avoid the chassis assembly comlexities The chassis contains 2 decks the lower is used for BO motors fitting the upper is used as a battery stack. On top plate the controller board is mounted by screw fitting.

Finally the Android application, You can get Bluecontrol app from Google Play

Multicontrol Robot - Control by GSM, Remote or Acclerometer http://www.8051projects.net/download.php?view.246 Multicontrol Robot - Control by GSM, Remote or Acclerometer with Project report

This project is an extention to previously uploaded "GSM Controlled Robot". Earlier project was only designed to be controlled using a mobile or GSM device whereas this project extends the control capabilities to custom designed RF Remote and A glove with Accelerometer.



This project is devided into two sections
1. Control/Encoder unit
2. Robot Unit

Control unit uses 433Mhz RF modules for sending control data to robot. Control unit receives data from either remote or an accelerometer module. Robot unit is actually the receving device which can receive data from either gsm device or RF recevier. Both RF reciever and GSM device send same kind of signals to control motors.

Control/encoder unit uses 8051 controller and its code is written in assembly whereas Robot unit uses AVR microcontroller, its source is written in C language. If you have already built the old GSM controlled robot then upgrading to this version of robot will not be difficult at all.

I have also added original project report came with GSM controlled robot, You can add more information in this project report to complete final report.

Here are working videos of project:

Viktor has share another project with us a great design with practical use. An 8051 based Solar tracker with source written in assembly language. He explains basic operation of this project.

PRINCIPLE OF OPERATION
The circuit comprises of three sections:
  1. light controlled circuit
  2. counter for timer
  3. switching circuit


1. Light controlled circuit:

This particular circuit controls other circuits. It puts the other circuit on or off depending the nature of the day. It comprises of LDR and transistor representation of smith trigger configured using two npn transistor(BC377) such that when there is a small potential difference across the LDR and variable resistor, The relay will be triggered to switch on other circuit. This circuit monitors day and night. The main function of this monitor is put off the device at night and turn it on in the mornining again.

2. counter for timer:
Since sun start from the east at 6:45am and set at exertly 12:45pm, the light controller circuit put on the whole circuit automatically making the timer to initialize its 6hrs counting sequence.

3. switching circuit:
This circuit is mainly used to control the direction of panel using a DC Actuator motor. Microcontroller AT89C2051 gets input from east and west Light control circuit and adjust panel to face sun direction.

Type of motor used:
24-36v d.c Actuator from super jack used in tv satalite dish polar adjustment

8051 based Inverter/UPS with inbuilt Charging system http://www.8051projects.net/download.php?view.244 8051 based Inverter/UPS with inbuilt Charging system

Well this is one of the most interesting and long awaited project uploaded on any microcontroller website. Its an Inverter/UPS with inbuilt charging system based on 8051 (AT89C2051) with a rating of 3000VA. As you all know an inverter converts DC voltage to AC, This project uses 24V DC battery and convert it to 220v 50Hz AC. Here are some pictures of constructed hardware.




The inverter system is divided into six sections:
  1. Inverter
  2. Charger
  3. Multivibrator
  4. Powerpack
  5. Sensors and Indicators
  6. Automatic changeover


8051 controller plays its major role in "Sensors and Indicators" section. 8051 is used to monitor the voltages and indicate status through LEDs. You can also find UPS test design for Proteus VSM simulator, to stimulate the design in case of any doubt. It is the same controller circuit as given in pdf. At89c2051 uses an active low to perform its operation from lm393 voltage comparator that's why a push button is connected to ground to test the circuit.

You can find pictures, code and small documenation that explains the working and block diagram of this project. Incase you have any doubts, feel free to post on our forum at www.8051projects.net/forum.html

I would like to thank Victor (ugoo5000) for sharing this awesome project

Automatic Room light Controller with Visitor Counter - Updated http://www.8051projects.net/download.php?view.119 Automatic Room light Controller with Visitor Counter

Project not tested

This Project "Automatic Room Light Controller with Visitor Counter using Microcontroller" is a reliable circuit that takes over the task of controlling the room lights as well us counting number of persons/visitors in the room very accurately. When somebody enters into the room then the counter is incremented by one and the light in the room will be switched ON and when any one leaves the room then the counter is decremented by one. The light will be only switched OFF until all the persons in the room go out. The total number of persons inside the room is also displayed on the seven segment displays.

The microcontroller does the above job. It receives the signals from the sensors, and this signal is operated under the control of software which is stored in ROM. Microcontroller continuously monitor the IR Sensors, When any object pass through the 555 timer generates a pulse and interrupt controller. So visitors in the room are counted up by Sensor1 and Sensor2 counts visitors going out of room. As soon as visitor count reaches 0 the room light turns off.

We already had this project in our download section but Anudeep (bobdxcool) had made it working. Thank you so much for sharing this project back.

DS1302 based Digital Clock with Calendar http://www.8051projects.net/download.php?view.242 DS1302 based Digital Clock with Calendar



Here is another great submission from Victor (ugoo5000). We do have many digital clock projects on website but I again wanted to add this one to our list because there are two new and interesting things in it. There are good things to learn from this project. So I summarize all of them here:

  1. DS1302 as Time keeping IC
  2. Interrupt based keypad


The DS1302 trickle-charge timekeeping chip contains a real-time clock/calendar and 31 bytes of static RAM. It communicates with a microprocessor via a simple serial interface. The real-time clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator. DS1302 communicates with microcontroller using a 3 wire interface a very similar to SPI. So this is one new thing to learn in this project.

Now second interesting thing which got my attention is interrupt based keypad. All codes we have seen till now uses keypad scanning. This one uses interrupt based approach for scanning keys. As soon as a key an interrupt is generated though an AND gate connected to all the rows, which indicate controller that a key is pressed. So scanning is done in ISR routine where key is detected. I am sure this way of using a keypad must be helpful fo many of us when making our new projects.
