How to Control Dc Motor with Arduino?
Here In this article, we will learn about DC motors and how these motors can be controlled using an Arduino board with very little programming. We are also going to use an L293D motor controller IC. This is very important to use the controller board because we can not connect the DC motors directly to the Arduino board. The power supply from an Arduino board is 3.3V and 5V which are insufficient to power a DC motor of 9V. If we try using Arduino there is a high risk of losing the Arduino board.
