Car Steering Mechanism: (refer to the schematics on as needed) When a command is received to turn left, the SCRX2BC creates a voltage at pin 7 which turns on transistor Q9. This then turns on Q11 and Q14 and current flows from the batteries through Q11, then through the steering motor, and then through Q14 to ground. This current through the Motor creates a magnetic field. Inside the motor is a small magnet which is connected to the gear you see on the outside of the motor. The magnetic field turns the magnet in the motor, which turns the gear. The “teeth” on the.
