hehehe!! Have you ever tried to do PWM with a relay? ;)
Sounds like a buzzer... and is not quite healthy for the relay...
Use LMD18200!!... altrough they are limited to 3A with a 5A peak... Can
somebody tell us if we can put two LMD18200 in parallel?

| REF: PWM control of 4A, 12 VDC motors with an LMD18200-based H-bridge HandyBoard Greetings, Two LMD18200s apparently can be 'bridged', being then capable of currents of 6A (average) and 12 A (peak). This information is based on specifications (...) (26 years ago, 25-Sep-98, to lugnet.robotics.handyboard)
