I need to control the speed of a 220v universal motor using arduino and I am thinking to use an atteny85 ic with a phase control circuit (ltv814 to detect zero crosses and moc3052 to drive a triac to clip the ac sine wave)
I found many example on the internet where people use the same method to control light bulbs and heaters
Will this way work with universal motors (that has brushes)?
If not what is the best way for that ?
Thank you in advance
