Hi everyone, My goal is to control the speed of a motor (connected to a fan) to control the exhaust temperature of a wood burning
I read a lot of articles about controlling AC motor with triac/opto but all of these solution involve to built the AC "shield" and i'm not confortable to play with 220VAC.
Currently my motor is controlled manually by a voltage dimmer connected to a rotary poteniometer. something like that: http://fr.aliexpress.com/item/1Pc-2000W-220V-Dimming-Dimmers-Thermostat-SCR-Speed-Controller-Voltage-Regulator-Newest/32555242468.html
I would like to know if it is possible to replace the rotaty dimmer by a digital potentiometer controlled by i2c.
