As well, this IC can drive small and quiet big motors. The Motor Driver is a module for motors that allows you to control the working speed and direction of two motors simultaneously .This Motor Driver is designed and developed based on L293D IC. It is designed to drive inductive loads such as solenoids, relays, DC motors, and bipolar stepper motors, as well as other high-current/high-voltage loads. As L293 output current for each channel is 650mA whereas it is 2A for L298. DC Motor in the late 19th century has its own use but after the discovery of AC motor by Nikola Tesla and a wide amount of usage of AC current in industry and houses. Motor Drive Module L293D High Voltage For L293D is a monolithic integrated, high voltage, high current, 4-channel driver. Note: There are total 4 ground pins in L293D IC because it has to deal with heavy currents. Connect 5v DC to EN1 and EN2 pin to operate the motor at its normal speed. This project is focused on designing and making our own L293D Motor Driver Module / Board that can be used for driving two DC Motor or one Stepper Motor or Solenoids. Here is an example of the circuit of street racing cars. EN1 and EN2 are enable pins. One suggestion to you is to align the motors. It attaches to its one end. These all above methods are usually used for the car. L293D shield is a driver board based on L293 IC, which can drive 4 DC motors and 2 stepper or Servo motors at the same time. L293D Adapter Board can be used as dual DC motor driver or bipolar stepper motor driver. So if you have motors which has operating voltage less than 36V and operating current less than 600mA, which are to be controlled by digital circuits like Op-Amp, 555 timers, digital gates or even Micron rollers like Arduino, PIC, ARM etc.. this IC will be the right choice for … The rotation will be anti-clockwise when Input 2 (Pin 7) & Enable (Pin 1) is high but Input 1 (Pin 2) is low. This will be the same for Input 3, Input 4 and enable 2. L293D Motor Driver Module. To control the max 600mA amount of current an internal “Darlington transistor sink” installed in it, which could be used to control a large amount of current by providing a small amount of current. In this tutorial i am going to teach you how to control speed and direction of dc motor using nodemcu WiFi module and l293d motor driver. There are 4 input pins for direction control in L293d. So, this pin should be supplied with 5 V. When this pin is given HIGH or logic 1, the output 4 becomes HIGH. H-bridge is the simplest circuit for changing polarity across the load connected to it. Output 1 is the input of the first motor/Motor 1. When this pin is given HIGH or Logic 1, the right side of the IC works and when it is low, the right side doesn’t work.
