Touch Car

You may be familiar to make different toy car. Do you ever tried to make a touch car? This student oriented project is to make a simple toy car and control it with your touch. Four touch sensitive switches are there in the Remote PCB to control the car in different directions. This low cost electronics project is very interesting to learn some basics of electronics components and motors. Do this project as a starting step to make high end projects using microcontrollers. Four touch switches in the PCB are wired to a motor driver L293D to control two motors. Just use your fingers and control the car.
