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.

LED Scrolling message Display using 8051





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:

Smart Home using GSM, Bluetooth and Android



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.

Go to download section to download this project: Smart Home using GSM, Bluetooth and Android

Finally the working Demo:

Arduino based GPS data Logger


Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists and anyone interested in creating interactive objects or environments. This is a very simple project based on Arduino and GPS sheild combo. Arduino provides good set of libraries which are easy to use and you can include in your project without any hassle.



As GPS usually works on serial ports, Software emulated serial port is used to connect GPS with arduino running at 4800bps. The hardware serial port is connected to PC for serial data logging. A 16x4 LCD is used for displaying GPS data locally. LCD provides GPS information related to Latitude, Longitude, Altitude and speed.



Its a very good project for starters, who wants to get their hands on with Arduino. I would like to thank Santosh Mishra for submitting this project. Hope to see more contribution from him.

To download this project Please visit download section: Arduino based GPS data Logger
