In this stage, there are two circuits: the car motor circuit and the car light circuit.

Car Motor Circuit

When a push switch is pushed, depending on the switch that it is (RF, RB, LF, LB) a motor will move on the direction of the switches name. For instance, if the RF switch is pressed, the LM will move right-forward; if the LB switch is pressed, the RM will move left-backwards; and so on.

Cars Light Circuit

If we want to the leds to works we need a resistance of 220 and a Battery of 4.5 volts plus three way switches to determine the direction of the current. This way, either the red or yellow LEDs will be on.
