AC PWM dimmer for Arduino
diy_bloke @ instructables.com has designed an AC PWM dimmer for Arduino: Over 3 years ago, I published a simpel TRIAC AC dimmer for the arduino. That proved to be a very popular design. Yet in spite of the simplicity of the circuit the software needed was a bit complicated as it...
