I found some related topics but they all concern Arduino diecimila or Arduino mega 1280; No one of them seems to explain what to do when arduino is 2560, and as far as I understand, the registers to change are different (the code working on 10000 does not work on 2560). I'm using the Arduino NANO. pin11 is connected to timer2 which is an 8 bit timer. Then set the overflow value to 3600 instead of 65535. TCCR2B = TCCR2B & 0b11111000 | 0x01; If you change the prescaler for a certain timer, you change the PWM frequency for the related PWM pins. That means <Servo. For Arduino Nano or Arduino UNO the PWM pins are 3,5,6,9,10 and 11.
