Four digital I/Os from the arduino (11,10,9,8), each of which are connected to the gate of an NPN transistor to handle about 30mA switching current, simulate the pressing of the four push-to-make contact switches on a simple r/c car remote control. This effectively gives a digitally-controlled forward, backward, left and right switch for the remote control car. This concept can be applied to any cheap remote-controlled toy. | Four digital I/Os from the arduino (11,10,9,8), each of which are connected to the gate of an NPN transistor to handle about 30mA switching current, simulate the pressing of the four push-to-make contact switches on a simple r/c car remote control. digitalWrite(pinX, HIGH); results in a pressed state and digitalWrite(pinX, LOW); results in an unpressed state. This effectively gives a digitally-controlled forward, backward, left and right switch for the remote control car. This concept can be applied to any cheap remote-controlled toy. | ||
