This project is used to control the brightness of the lamp or can be used to control the speed of the fan. The system consists of 3 block they are Zero crossing detector Microcontroller (Atmega8) Load Driver (BT136)As the name implies the zero crossing detector generates pulses for every zero crossing of the input AC …
When my little girl was born I wanted to make her a special night light for in her room. I made her a ceiling light with twinkling stars. It is made up of a piece of custom wood with 100 LEDs mounted in it. An AVR AT90S8538 micro controller runs a bascom program that produces …

This is merely an instructable to explain how this device operates. I hope everything is not too obfuscated. This prototype consists of three 8×8” modules. Each module operates independently of each other. Each module consists of 4 “pixels”. Each pixel is 4 inches square and consists of 21 LEDs, two IR emitting diodes, and two …
Who wants to go outside to see if the mail has arrived? In the cold winter or rain I’d rather not have to put on a jacket and shoes, only to find that there was no mail. This project will notify you of the mail carrier’s visit, and as a secondary function it will remind …

This project describes an automatic light system for kitchen sink where you need sufficient light to properly clean your dishes and vegetables. It uses an ATTiny84 microcontroller with a PIR motion sensor. When motion is detected, the microcontroller turns on the light. The light source consists of 10 bright white LEDs that are driven by a IRF612 …
