Arduino and L293D Robot ( Part 1 )

Arduino L293D Robot

Here is part 1 of the Arduino and L293D Robot.This is part of a series of instructables leading to a Line follower Robot.

This is a basic Robot made by controlling two motors via the L293D chip through an Arduino Board.

I have done this project in the past with similar set up just not with an Arduino Board.

Do let me know what you think of this project and if I made any mistakes.

Step 1: Parts

Arduino Board 

Breadboard

L293D Chip

Two Motors

9 Volt Battery

6 Volt Battery Pack

Arduino L293D Robot

Step 2: Wiring the L293D Chip

Pin 4 ,Pin 5,Pin 12 and Pin 13 from L293D Chip Connect to Ground (Negative On Breadboard)

Pin 1,Pin 9 and Pin 16 from L293D Chip Connect to 5 Volts (Positive On Breadboard)

Pin 8 from L293D Chip Connects to 6 Volts (Positive On Breadboard)

Pin 3 from L293D Chip Connects to Right Motor
Pin 6 from L293D Chip Connects to Right Motor

Pin 11 from L293D Chip Connects to Left Motor
Pin 14 from L293D Chip Connects to Left Motor

Output pins on Arduino to control Right Motor :
Pin 2 from L293D Chip Connects to Output Pin on Arduino
