Multiple Interrupts in INT0 But only one signal - [ SOLVED ]
AbDoO_ wrote: the point of using The INT0 instead of the regular input test  is because i want it to be fast and with no extra coding . Thanks for Suggesting .   ...

Multiple Interrupts in INT0 But only one signal - [ SOLVED ]
If your comparator simply compares two voltages, its sensitive to noise, and may oscillate when the two voltafges are near identical. That will trigger multiple times.  ...

24V 3A ampere motor drive using atmega32 pwm
I would also add a resistor at about 220R between atmega and mosfet gate. At low frequency it should work as long as gate voltage can turn the mosfet properly on. Reason for...

1 Watt or 2 watt Resistor
Wattage depends on surface. Double long, double wide => 8 x surface == 8 x wattage == 1W.   Resistors are dirt cheap. Does reuse pay off?
