AVR: Introduction to AVR through a simple program.

Post Thumbnail of AVR: Introduction to AVR through a simple program.

AVR are RISC based microcontroller made by ATMEL. This post introduces AVR by the help of a simple program which toggles a LED. It is achieved by the help of WinAVR and ATMEL AVR-Studio. ATMEGA8 is used and is programmed in C Language. Continue reading

This is a simple and small sample demonstrating basic interfacing of 16×2 LCD with PIC16F876. It uses PORTC for LCD, and workd upon 4-Bit.
Upon running the sample, “CreativeElectron” will be displayed on the LCD.
The Zip file contains;

- Source Code and Header File (.C)
- Proteus Working Simulation (.DSN)
- Image file of Design Continue reading

Project Link: Distance Detecting PC

A sonar rangefinder, an Arduino, and some clever programming, he’s made is computer react to his distance from it. As you can see in the video after the jump, he has programmed it to change text size and background color depending on his distance from the screen. While he admits that his implementation doesn’t seem immediately useful, there’s lots of potential  there. Continue reading

Photography: High-Speed Photography using Microphone

Post Thumbnail of Photography: High-Speed Photography using Microphone

In this project a microphone is used to activate flash, creating immense time-critical photographs. He uses sound activity as a trigger, by setting microphone under a tin sheet. The water drops on tin sheet creates a sound and hence ends up triggering the strobe. Simple idea in electronics but goes a long way in photography. Continue reading
