A White LED Night Light Design

BUT FIRST AN IMPORTANT NOTE: This project uses lethal voltages.  If you are not experienced in working with lethal voltages, read this project, but don't build it. You only have one life, and AC power can take it from you very quickly, or leave you with terrible injuries. When working on high voltages, remember: • Keep one hand in you back pocket. Don't provide a path through your heart. • Use and insulated ...

An Isolated Adjustable Auto transformer using microcontroller

This is a means of testing AC mains operated circuits at variable AC voltages, and it also provides isolation to allow safe measurements of that circuit.   A fused isolation transformer and a variable auto transformer connected together in a grounded, fire safe box. What more could you ask? Find updates at www.projects.cappels.org   Introduction I need to be able to test and measure the operation ...

Relay Timer with ATmega8 AVR MCU

Timers are widely used in industrial and domestic application for automating tasks. Microcontrollers can be used to design versatile and accurate timers with ease. Here I present a simple timer that can be used to turn on/off a load after user specified time. The Timer uses a standard 16x2 lcd module for user interface (UI). User can set the time using a 3 button keypad. After that Timer is started. While c ...

Remote Controlled Fan Regulator using ATmega8 microcontroller

This device can be used to remotely control the speed of an AC fan and to switch it on or off. The remote control is a cheap NEC Format remote, usually supplied with small DVD players. Three buttons are used to command the circuit. The UP key increase the fan's speed while the DOWN key decrease it. The ENTER key is used to switch on or off the fan. The unit provides 10 way speed control from 0 to 9. The cur ...

AVR LED Candle using ATtiny85 microcontroller

This LED candle is built to mimic the look of a traditional candle without the dangers associated with an open flame. It uses high brightness LED and is controlled by ATtiny85. It could be useful as movie props where you cannot afford to have a candle go out during a take or in your home in places not suitable for traditional candles such as in a wall niche or alcove. Pete made this candle with a Light Dete ...
