I need to measure RPM of motor. I have magnetic sensor, (magnet with coil) which is interface with LM324, the output of lm324 given to ATMega88PA, Input Capture Pin, so i need a exact pulse signal, i have designed some circuit, but this circuit does not produce constant pulses, if any expert in this area, help me!...
