A simple DC motor controller circuit using NE555 is apparent here. Many DC motor acceleration ascendancy circuits accept been appear actuality but this is the aboriginal one appliance NE555 timer IC. In accession to authoritative the motors acceleration its administration of circling can be aswell afflicted appliance this circuit.

A PWM circuit based on timer NE555 is the affection of this circuit. NE555 is active as an astable multivibrator whose assignment aeon can be adapted by capricious the POT R1. The achievement of IC1 is accompanying to the abject of transistor Q1 which drives the motor according to the PWM arresting accessible at its base. College the assignment aeon the boilerplate voltage beyond motor will be top which after-effects in college motor acceleration and carnality versa. Change of DC motor administration is accomplished appliance the DPDT about-face S1 which on appliance just toggles the polarity activated to the motor.
