You all may be thinking how to make it without programming
Here it is Without Programming.
In this instruct able i have used only ICs. It is very very easy to make. Circuit is very easy but the mechanical is very tough.
Thing you will need-
1)A Caster Wheel
2)A big body of a car, You could buy or make it.(But i have made it)
1)L293D IC (three ICs)
2)1 Rocket switch
3)10 tactical switches
4)Breadboard (You can use 1,2,3or4 and so on,it depends on you how would you like the circuit look)
5)3 LM 7805 IC (It converts 9v to 5 volts)
6)1 Heat sink (but i have used two)
7)Breadboard wires or wire you think is perfect for breadboard
8)Two geared motors of low RPM
9)One motor of medium rpm which rotates slowly
10)Two motors of 100-200 RPM
