Tell us about yourself!
I don't know what motor you'll be using and what its stall-current is, but this h bridge can handle up yo 43 amps. Guess that should be sufficient for a regular wiper motor.
No, that would never work with a wiper motor; even without any load, the motor would pull so much current the h-bridge would be fried instantly. The data sheet of any h-bridge will tell you the current it can safely support.
You can use the serial monitor in the Arduino IDE to see what value the potmeter is giving. That might give you wome hints as to what is wrong. Just send the potmeter value to the serial port using the serial.println() function. Then open the serial monitor from the IDE menu while the code is running.
If you open the zip using 7zip you'll find the three files.
Thanks!I'm using this setup in my motion sim racing simulator. Using PID would require to continuously update the Setpoint, which would wreck the D and the I.

Hi there, and thanks!That would require two changes: first, you have to find the pot value for 0 degrees and set the MIN_POT_VALUE in the header file (MegaServo.h) to that value and second, you have to set MIN_ANGLE in the same file (two lines below) to 0. Make sure the adapted header file is the one that is actually used by the Arduino IDE compiler!
