Programmable LED dimmer

A Programmable LED dimmer from Soldernerd: Around one and a half years ago I’ve designed and built various LED dimmers for both white and RGB LEDs. Then late last year someone approached me asking if I could make an RGB dimmer for him, too. But my designs were really tailored to...

230V AC dimmer, mains isolated, using PIC12F629

This is a very simple mains isolated dimmer with a triac output (phase control). It uses timer0 to do the timing. There is no user interface, the value of the triac ignition delay after a zero crossing is defined by setting the reload value of timer0 (Tmr0) in the software...

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...

PWM dimmer for RGB LED

Lukas Fassler has designed and built a PWM dimmer for RGB LED: In my last post I’ve described the design and construction of my LED dimmer project. This project here is similar but a bit more involved. It controls RGB LEDs so it can not only change the brightness but also the color...

PWM dimmer for LED lighting

Lukas Fassler has published a new project, a DIY PWM dimmer for LED lighting. The dimmer can handle [email protected] and is controlled by a single potentiometer. I have recently moved to a new apartment and was looking for a PWM dimmer to control some 12V LED strips. I thought that should be...
