Abstract :
The LED head directed motorized chair is designed to assist a client with cerebral palsy. The wheelchair uses an LED display panel in coordination with a head switch as a control apparatus to drive the wheelchair under the control of the client. This design uses a microcontroller to coordinate sensor information and to enable the motor driver circuits. The client depresses the head switch when the appropriate direction on the LED display appears, thus engaging the motor driver circuit. The motor circuits consist of two pulse width modulators that control forward or reverse direction, and speed of the motors. These are the central drive circuits that control the motor direction
