Circuit mainly consists of sensor part which includes tape sensor and beacon
sensor, and actuator part which includes main motor drive and door lock motor
drive. We used one 7V, and one 14V voltage supply ( two 7V batteries in series).
7V supply was used to drive two main motors and14V supply was used for all
other circuits and microcontrollers after it was regulated to 5V by LM7805
voltage regulator. Please click on the part name for detail.
