I have a sensor circuit that also connects to a small vibration motor. The Motor plays havoc with the power lines! So much so that the sensor will not work while the motor is running. It is definately not the vibrations causing the problem. Can anyone suggest a suitable circuit to run a 1.6v 80mA(start up) 40mA(continuous) vibration motor from a 5v regulated(7805) supply. The driving signal will come from a microcontroller. Many Thanx
