hello everyone.
I am making a three phase inverter to control the speed of induction motor placed at the O/P of inverter.
I am using potentiometer as analog input and using it to vary the duty cycle and freq of gate signals.
I am facing an issue right now. arduino UNO has 6 PWM pins. I am using them to get 6 gate signals but only three pins( 9 10 11) are generating PWM signal with desired duty cycle. PIN 3 5 6 are generating digital "high" signal but not the analog PWM signal. My code is fine. I have tested it on arduino MEGA. I am getting 6 PWM outputs with desired freq and gate signals on PWM pin 2 3 5 6 7 8. I want to get it right for arduino UNO if possible.
regards,
