About The Guide: The guide includes the datasheet, schematic diagram, PCB layout, Arduino test files and etc. Cost: It only cost me P363.75 ( Converted: $8.87)! The prices would decrease to P262.50 (Converted: $6.40) if I sticked to the original plan, since it's for competitional purposes, I substituted some parts with a higher rate of response. The Arduino Board (Microcontroller) itself isn't designed to operate high current loads, that's why we use motor shields, it is a circuit that is controlled by your arduino board to drive high power accessories.
What Is A Motor Shield? A motor shield is a circuit that drives different loads such as motors, lights and etc. With the help of eight fast recovery diodes (1N4937) it shows a very fast response of stopping/ braking, that's why I'm going to use it for the national SUMOBOT competition. The connections are: 11&10 for the R-Motor and 6&5 for the L-Motor. Structure: It's controlled using 4 PWM pins. The original Arduino motor shield has the same motor driver chip (L298), the only difference with it, is the package type, my project contains the vertical version of the chip L298 (with a 'N'). It works splendidly, its posses almost all the characteristics of the original Arduino motor shield.
Today, I'm going to show you how to make an Arduino motor shield (driver) at a low cost.
