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.
Project credit goes to:
Parambir Singh Mattewal (Supervisor)
Thank you guys for submitting this project.

Simple 3 Digit Temperature Meter
This project is a simple temperature meter using LM35 analog sensor connected to PIC microcontroller PIC16F676. The temprature is displayed on 3 digit 7-segment display. Project code is written in C language for CSS compiler for PIC. Here are few things that you can expect to learn from this project:
1. Using Analog port of PIC Microcontroller
2. Interfacing LM35 temperature sensor
3. Interfacing 7-segment display
4. Multiplexing multiple 7-segment display
Simple yet so much to learn in this project. If you are a starting to learn microcontrollers then this is your project. The download package also includes a proteus simulation so you can modify and test this code before building the actual hardware.
I want to thank Rakesh Suthar for submitting this project. I hope to see more learning oriented project from him.
Download Package Content:
- main.c : Project C code
- main.hex : Hex file
- schematic.PDF : Schematic file
- lm35-temp-meter.pdsprj : Proteus simulation Project file
If you have any questions or queries on this project feel free to ask in forum.

This Project is a scrolling LED matrix display project using 8051 (AT89S52) controller and 24C16 EEPROM. This LED matrix project is designed to work flexibly to handle 1x18 matrices of 8x8 LEDs or 1 to 29 matrices of 5x7 LEDs. The total matrices support can go higher if a controller with higher RAM is used. You do not need to do any change in the program for that. There is also a software provided to upload your message from PC to EEPROM.
This project is submitted by Pratik Suthar of Government Engineering Collage, Dahod (Gujrat). I really want to thank him for his contribution to Rickey's World.
Now a working video of the project:

This project demonstrates a great concept of Home automation using a Smart Home Device which can control things automatically by taking decisions based on sensor network and external events or manual control using your phone over Bluetooth or GSM. Which means if you are inside the house you can use You can control your appliances using bluetooth when outside use your GSM phone (over SMS).
This project uses AVR controller ATMega328 running Arduino firmware. There are a number of sensors connected to the controller some on GPIOs and some via Analog ports. Here is a short list of sensors:
1. Temperature Sensor (LM35)
2. PIR Sensor
3. Light Sensor (LDR)
4. GAS Sensor
Wireless modules used in this project:
1. SIM300 GSM Module (SIM900 can also be used)
2. HC-05 Bluetooth Module
There is also a provision for controlling 4 AC appliances. One LCD is also connected to show real-time status of all the sensors.
This project gives a good hands on practice on AVR controller and Arduino firmware programming. With various communication options one can get good experience on wireless communication. Further more there are endless possibilities of expanding this project. So you really need to turn your brains on and think of what more you can do with this.
Project also includes complete documentation including Synopsis, Project report and final presentation. But don't get carried away with these goodies. Learn and Build this project so it can benefit you in future
I really want to thank Gaurav Khadasane once again for submitting this wonderful project and bringing lot of things together to learn in a single project.
