Hi,
This is a basic code for DC motor speed control, speed vary in function of a potentiometer position
If you want to vary the speed of an AC motor... this is an other thing... this is called an inverter. Your motor must be 3 phases AC, you need to rectify your 220Vac in to DC volts and build 3 H-bridge to generate 3 phases pattern of modified sine wave (not square wave)... this is not the best, but it work great!!! the hardest part is probably the current limiting circuit
Hope this help
