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

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. Specifications  Supply 5 to 12 V Inhibit facility/enable PWM Frequency 5KHz Maximum High
