WhereasL298N has the advantage of higher output current up to 2A and therefore it is suitable for high torque and high RPM motors like Johnson motors and high torque DC Geared motors. The L293D is a 16-pin Motor Driver IC which can control up to two DC motors simultaneously, in any direction. DC Motor Speed Control (PWM) Lab Number: 14: Lab Level: Beginner: Lab Objectives: Learn how to use PWM signal to control the speed of a DC Motor. L293D shield is a driver board based on L293 IC, which can drive 4 DC motors and 2 … A single L293D IC is capable of running two DC motors at the same time; also the direction of these two motors can be controlled independently. L293D Motor Driver IC. Drive a DC motor forward and in reverse with variable speed. I have tried circuit after circuit from the internet, and the best I have done is to get control in one direction only. Also while doing the connections the Pi2 module should be off to avoid damages due to shorting by mistakes. I am trying to build a circuit using the L293d h-bridge. Remember, the stepper and dc motor connections will not work if the onboard green indicator LED is not lit brightly! DC Motor Interfacing using L293D with PIC18F4550. As the motor needs about 400 mA current to start, It could not produced by the Pi, and the Pi will be damaged. Also, you should be using an L293D Motor Driver IC in order to control the direction of motor’s rotation. Before we start the wiring. L293D Piggybacking – High Current DC Motor Driver.
