Arduino PWM Pins 3 And 11 Are Not Working While Using Timer1
Maybe your like
Hi guys,
I have been working on a project in which I need to use Timer1 interrupt and as well as PWM pins 3 and 11 for controlling the steering and the speed of my car. It seems that when I use Timer 1 pins 3 and 11 stop working. Please can anyone guide me through where am I going wrong?

Use a different timer, if you must use pins 3 and 11 for PWM.
DakshGupta February 27, 2016, 12:20am 3Hi, Thank you for your response. I am confused. So if we use timer 1 on Arduino Uno it breaks the AnalogWrite() on pins 9 and 10. And as you say it might be using pins 3 and 11 as well. Hence does that mean I can use only pins 5 and 6 for controlling the servos?
DakshGupta February 27, 2016, 12:32am 4Hi, I tried using pins 5 and 6 as well but it seems that when I initialise Timer1 and attach Timer1 interrupt none of the PWM seems to be working. I am using the servo library to control the motors. Hence I am unable to control the steering and speed from any of the PWM pins if I use Timer 1. Please help
DakshGupta February 27, 2016, 12:44am 5I guess I found the solution. Timer 1 is reserved for Servo library hence if I try to use it separately the servo library doesnt work on any pwm pin. Please correct me if I am wrong.
