Makerfabs has introduced the MaTouch 1.28-inch ToolSet AC Dimmer, an open-source AC voltage controller based on the ESP32-S3. It is designed to dim lights and control motor speeds using phase-cut dimming. The device features an ESP32-S3 wireless MCU with 16MB flash and 8MB PSRAM, along...

From small LED drivers to rectifiers to Switch Mode Power Supplies (SMPS), the diode is a key component in each of those everyday appliances. They are also used in charging LED indicators and reverse polarity protection circuits in router chargers and many more; diodes are used...

This IR remote controlled dimmer works with a triac and in its standard configuration is suitable for light electric heaters and incandescent lamps up to about 1000 watts. The PIC microcontroller used in the project can learn control codes from almost any remote control. Here’s power...

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...

Dark Sensitive Lamp controller project switches a load connected to it when light falling on LDR (Light Dependent Resistor)  goes bellow set point.  It could be used as an automatic street light application. The project is based on Triac and doesn’t requires additional DC supply,...

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...

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...

This low cost current feedback phase control AC motor driver based on U2008 IC, The U2008B is designed as a phase control circuit in bipolar technology. It enables load-current detection as well as mains-compensated phase control. Motor control with load-current feedback and overload...
