Hi, I´m doing a university project with arduino. The device controls the speed and the position of a motor with the PWM pins. My problem is that most of my digital pins have a constant voltage, when its should be a 0v, because I don´t use these pins in my program.
And I have notice that my arduino (only the chip ATMega 328) is too hot, so I though that I had fried my arduino, but I can load some programs like the blink led, and it works, but I still have mos t of my digital pin with a constant voltage. Can somebody help me?
