DC Motor Speed and Direction Controller for Low Voltage Motors Using L293D & 555 Timer

DC MOTOR SPEED AND DIRECTION CONTROLLER USING L293 AND 555 TIMER (1)

DC Motor Speed and direction controller project based on L293D H-Bridge and 555 Timer IC. 555 Generate PWM and L293D works as output driver. The 293D provides bidirectional drive current up to 600mA a voltage from 5V to 12V. L293D includes the output clamping diodes for protections.
