In this example, when a pushbutton connected to digital pin 2 is pressed, the Arduino will control a transistor via pulse-width modulation (PWM), which will ramp up the motor's speed, then slow it back down. Another set up consisted of half bridge rectifier consisting of thyristor wherein the speed control for the same DC motor was carried out using the firing angle of the thyristor. We are able to control the direction of an AC motor from arduino uno, and still allow any manual control from the pendent switch (when arduino is not running). Although that is how the previous products we made have worked. Dimmer Library for Arduino¶. A triac is a three-terminal (MT1, gate, and MT2) solid-state thyristor that uses the alternative symbols in Figure 1 and acts like a pair of SCRs wired in inverse parallel and controlled via a single gate terminal. You are correct, an induction motor will not vary in speed by Triac or Variac control, as it attempts to run at near synchronism. Therefore, we always face the situations that we want to have full control (dimming) over an AC load such as a lamp, a motor, vacuum cleaner … etc. Another way is pulse skip modulation which is not good for most of the AC appliances. 100% Quality.

In this tutorial we will design a circuit using TRIAC and optocoupler to make a 220V AC Light Dimmer or AC Fan Speed Controller using Arduino. I guess that's not the case with Arduino Nano since it uses PWM signal? Or do I still need the NAND-gate? And if someone would like to explain why the zero-crossing TRIAC driver doesn't accept certain signals, I would be grateful. The net result here is that we “chop” parts of the wave out resulting in lower average power. Controlling the speed of an AC motor is not an easy undertaking, and messing around with mains voltages if you're not experienced and know what you're doing can be fatal. Component Description Arduino Uno Board. Thyristor behaves like Electronic Latch while using as a switch, because when triggered once it remain in conduction state until getting reset manually. You will also use an arduino analog output(PWM) to control the speed of the motor by sending a number between 0-255 from digital pin of arduino. A-T Controls, Inc. I tested with 12V halogen lamp, it worked too. not overloaded]), and a relatively simple interface to the arduino. The duty cycle of PWM will control the motor using an optocoupler to trigger the TRIAC. In this example, when a pushbutton connected to digital pin 2 is pressed, the Arduino will control a transistor via pulse-width modulation (PWM), which will ramp up the motor's speed, then slow it back down.
