Arduino and L293D Robot ( Part 1 )

Summary of Arduino and L293D Robot ( Part 1 )


This article details the assembly of a basic Arduino-controlled robot using an L293D motor driver chip to manage two motors. It guides through wiring the L293D chip to the Arduino board and motors, detailing connections for power (5V and 6V), ground, and control pins from the Arduino to the chip. The project serves as a foundation leading toward building a line follower robot.

Parts used in the Arduino and L293D Robot:

  • Arduino Board
  • Breadboard
  • L293D Chip
  • Two Motors
  • 9 Volt Battery
  • 6 Volt Battery Pack

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.
