Hello This is my first Arduino project. I am trying to build a controller for a Mercedes Benz radiator cooling fan. The fan controller operates at 5V@ 10Hz. PWM signal between 0 to 90% duty cycle. At the moment I have just built a system using a 10K pot to simulate a thremister all works fine exc…

I did solve the problem. After a little reading I found that a special special high resolution command is required to get 16 bit resolution for frequencies from 1Hz to 2MHz. It also only works on pin's 9 and 10 on the RoboRed. The following changes made it work Set the fan pin to pin 9 using int F…

I did notice that. But it was scary.
