Abstract
In the present study, innovative idea of touchpad controlled vehicle and its real life implication is described. Generally in such system touchpad is interfaced with ADC (0808/MCP 3208) which gives the co- ordinates of the points touch by the user on touchpad. But in this research work Programmable Intercombination Circuit (PIC) (18F4550/18C4550) is used purposefully instead of ADC as input signal were in analog which required converting into digital signal. PIC can be used to interface touchpad and also perform serial port programming far better than ADC. PIC gives output to 8051 microcontroller which uses keil software program in C for input and output programming. Test drive was done to crosscheck the performance of touchpad as well as vehicle and it was observed that car was running at corresponding given location directed by touchpad at al instants. Keywords - Touch screen, PIC 18F4550, Motor driverL293D, RF Transmitter & Receiver, Keil software.
