ABSTRACT:
A remote-control vehicle includes a controller that produces a pulse-width modulated (PWM) motor control signal and a forward/reverse motor control signal in response to a transmitted digital signal specifying one of a multiplicity of speed control states, each of which has a direction and a PWM duty cycle associated therewith. A MOSFET switch turns on and off in response to the PWM signal to control the flow of current between a battery and a motor to thereby control the speed of the motor. A relay, coupled between the battery and the motor, switches in response to the forward/reverse signal to change the direction of current flow through the motor to thereby control the direction of the motor.
