This will only work with a random fire optocoupler: NOT igniting at zerocrossing is the principle of this dimmer. Switching an AC load with an Arduino is rather simpel: either a mechanical relay or a solid state relay with an optically isolated Triac. Over years ago, I published a simpel TRIAC AC dimmer for the arduino. Yet in spite of the simplicity of the circuit the software needed was a bit complicated as it needed to keep track of the zero crossing of the AC signal, then keep track of the time and then finally . Dimmer Library for Arduino.
This is an Arduino software library to control AC loads using triacs and a zero cross detector circuit.
The library methods can be used to control the AC load power for multiple triacs independently, using a single shared zero-cross circuit. Use an Arduino to make a dimmer and control the brightness of a lamp. We will design a Pulse Wave Modulated (PWM) dimmer circuit which will use an IRF830A in a diode bridge which is used to control the voltage across the bulb.
Measuring with a 100W bulb, the voltage across a 230V mains supply is just 2. I have discover two ways so that to dimm a incadence 230V bulb using Arduino. Both uses a triac but the main difference is how arduino should understand the zero cross detection of AC. This method is called AC phase control.
It is the method used in many light dimmer and heater and motor power control . With Arduino , we can made control with potentiometer (like in shops) or with push buttons.
I use 100W incandescent bulb at . Hi Blynkers, I wanted to share with you this little project. One method of controlling power to AC circuits uses a TRIAC to turn the power on and off at precisely timed intervals that are synchronized with the AC signal. AC Phase Control Circuit ( Dimming Circuit). Module contains a Triac triggering coupled with zero-cross detector mechanism for programming the intensity of incandescent lamps, heating elements or fan speed controlled through a micro- controller. Working voltage from 110v to 240v.
Auto detect 50Hz or 60Hz. It becomes a bit more tricky if one wants to dim a mains AC lamp with an arduino : just limiting the current through a Triac is not really possible due to the .

Module contains two Triacs with zero-cross detector for programming the intensity of incandescent lamps, AC LED dimmable bulbs, heating elements or fan speed controlled through a micro-controller. Eliminate ac wiring when dimming ac incandescent and LED holiday light strings by using the PowerSSR Tail.
Control light intensity of 220V AC lamp over Bluetooth using Arduino and RoboRemo app Disclaimer. Диммер 220в для ардуинки. Планировал сделать на одной плате сразу штук что бы управлять светом во всём доме!
The delay functions cause the CPU to loop and no other processing can be done.
