In the kit DC Motor Control using a Single Switch DC motor will be run in clockwise or anti-clockwise direction and stop it using a single switch. It provides a constant voltage for proper operation of the motor.
The kit DC Motor Control Using a Single Switch consists of three units- 555 as mono stable vibrator, as the decoder and flip-flop unit to hold the state and shift the bits and the motor driver unit to drive the motor in both the direction. All the controls of the motor are with the single switch that is forward backward and stop. The 555 unit gives a trigger pulse on each press of the switch. To prevent the false triggering 555 timer is used in mono stable mode. Every trigger pulse changes the logic state of the output of the CD4017 which gives high polarity on different pins (+9V).The potential divider circuit distribute this voltage (formed by two equal 10K resistors V=4.5V). These signals are fed to the motor driver IC L293D to operate the motor in both the direction. First press of the switch operates the motor in forward direction by giving 4.5V to signal pin. Similarly, second press of the switch operates the motor in backward direction by giving 4.5V to signal pin. The third press of the switch will reset the IC CD4017 to give 0V output to both the signal pins and thus the motor stops.
