Whistle based remote control using Attiny2313

The advantage of having remote control is avoiding wires. This gives some freedom to place devices anywhere around. Traditional remote control requires a transmitter device which isn’t very handy is some situations – you have to find it first… what about having a remote where you don’t need a transmitter. There you have many options like clap, voice activated and other you can think of. Befin made a whistle activated controller. He used an Attiny2313 microcontroller with microphone attached to it. Then he hooked RF remote outlets to it to be able switching various devices in a house. This wouldn’t be that simple without using a PC. AVR microcontroller has a V-USB running that allows connecting it to PC running Linux. This is where magic happens. Once MCU captures sound … Continue reading
