To learn more about L293D, do not miss this article: L293D: Theory, Diagram, Simulation & Pinout. In this project, you will learn how to drive motors with L293 and Arduino UNO as the controller. L293D can also be used to drive servo motors. L293D is one of the most popular motor drivers to run DC motors with up to 1A current load.L293D has 4 outputs which makes it suitable for 4-wire stepper motors. Motor drivers can be connected to the microcontroller to receive commands and run the motor with a high current. To solve this, we should use a motor driver. For example, Arduino UNO pins are limited to 40mA of current which is far less than the 100-200mA current necessary to control a small hobby motor. But there is a problem Microcontrollers cannot provide enough current to run the motor and if you connect the motor to the microcontroller directly, you may damage the microcontroller. These requirements can be handled by using a microcontroller (or a development board like Arduino). In addition, spinning direction and speed are two important parameters to be controlled. ĭriving electromotors needs a high current. If you do not know what L293D is, we suggest reading L293D: Theory, Diagram, Simulation & Pinout. At the end of this tutorial, you should be able to control spinning direction, acceleration, speed, power and shaft position. In this article, you will learn how to control DC, Stepper, and servo motors by Arduino and L293D.
