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 . You will also find a schedule here. Hi Blynkers, I wanted to share with you this little project.
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. Switching an AC load with an Arduino is rather simpel: either a mechanical Relay or a solid state relay with an optically isolated Triac. 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 . Almost years ago, I published a simpel TRIAC AC dimmer for the arduino. AC dimmer using IGBT transistor chopping the sine wave according to PWM output from Arduino.
FREE ARDUINO codes for ARDUINO and RASPBERRY boards. Compatible with any ARDUINO, RASPBERRY boards. How to connect AC Control Module to ARDUINO UNO board Arduino code for ATMEGA328P microcontrollers (MICRO, NANO, UNO Boards)-here. 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. By changing the voltage waveform applied to the lamp, it is possible to lower the intensity of the light output. Although variable-voltage devices are used for various purposes, the term dimmer is generally reserved for those intended to control light output from . This AC dimmer circuit utilizes a zero crossing detector and Triac. The output power can be controlled by adjusting a potentiometer value. The max current allowed is 10A (limited by the Triac).
This device can control the power delivered to any type of AC device, not just lamps. It can work on AC motors, . Our latest batch shipping from Sep 1st will include a new diode bridge so that it can withstand 240V. However you need to change the R Rresistors to . Adapted by DIY_bloke License: Creative Commons Attribution Share-Alike 3. Attach the Zero cross pin of the module to Arduino External Interrupt pin Select the . Parts are relatively cheap! This is a very simple mains isolated dimmer with a triac output (phase control).
It uses timerto do the timing. Your schematic has wires running across chips and between the plates of a capacitor! This is going to make it difficult for anyone to debug – including you.
You need to give designators to each component so we can discuss them. R R C C Q Q .
