This study deals with innovative idea of touchpad controlled vehicle. Normally 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 study 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 vehicle and it was found that car was moving at correspond given position. Car was moving as directed by touch screen at given location.
