Tiny Isolated Dimmer with Linearly Corrected Output

Dimmers provide a way to reduce the power of resistive elements like heaters and light features by changing the waveform of the voltage applied to them. There are different approaches to the development/implementation of dimmers and there are a lot of how-to guides and projects based on...

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...

Arduino controlled Triac light dimmer

diy_bloke @ instructables.com has build an arduino controlled triac light dimmer and describes the circuit and software used to achieve that. It becomes a bit more tricky if one wants to dim a mains AC lamp with an arduino: just limiting the current through e.g. a transistor is not...
