Self Driving Cars Using Arduino

 Self-Driving Cars using Arduino Uno.

• Introduction in Self-Driving Cars.

even though this Arduino Bot cannot be completely considered as "self-driving" but performs some similar tasks, the project is designed using cheap and readily available children's RC toy cars. The circuitry inside the bot is removed and replaced with an Arduino UNO or any kind of such microprocessors. The car contains a selector through which the user can select the operation mode, preferably there are three types of operations, one which includes line following and a special programme which allows the car to use ultrasonic sensors and infrared sensors to detect and block obstacles. the ultrasonic system can also traverso through tracks with walls, the third operation uses the same hardware as the second operation but uses a different algorithm, the main intent of such a program is to navigate in a straight track with no walls but contain obstacles, the process by which the Bot does so will be explained later throughout this page.

HARDWARE

The hardware of this product is simple, the major driving elements are all packed within the toy car, the turning mechanism etc, this should not be disturbed.
They generally come in a system with two motors, on responsible for the actual motion and the other motor is responsible for controlling the turning of the car. The turning mechanism contains rack and pinion which turns the wheels.

We will not touch any of these, disclaimer don't even try to unscrew those.
you will use a wire cutter or solder to remove the logic board, the battery wiring etc. the motors will be driven using the battery system available with the car the Arduino will have a +9V battery.
for this project, I will use a 4.8V AA700mAh Ni-Cd Rechargeable battery it can drive the battery
