How to Use the LD Motor Driver – Arduino Tutorial: The LD is a pin Motor Driver IC which can control a set of two DC motors simultaneously in any. SunFounder LD is a monolithic integrated, high voltage, high current, 4- channel driver. Basically this means using this chip you can use DC. The Motor Driver is a module for motors that allows you to control the working speed and direction of two motors Motor Driver is designed .

Retrieved from ” http: It is designed to provide bidirectional drive currents of up to mA at voltages from 4.

Drivers are enabled in pairs, with drivers 1 and 2 enabled by 1,2EN and drivers 3 and 4 enabled by 3,4EN. When the enable input is low, those drivers are disabled, and their outputs are off and in the high-impedance state.

LB is another IC of L series having. The schematic diagram is as follows: This is really nice to read content of this blog. LD has 2 Channels. Interface GPS with Arduino. SPI Module of Arduino. From m i crocontro l ler we can not connect a m o tor directly because m i crocontroller can not give sufficie n t current to drive the DC m o tors. Call and get core Job. Every Arduino Microcontroller has a circuit diagram and source code. This is what is used in this self-balancing robot project.


Enable pins 1 and 9 corresponding to the two motors must be high for motors to start operating.

This is a m o tor driver IC that can drive two m o tor si m u ltaneously. Logical Supply Voltage will decide what value of input voltage should be.

Diac Drived May 10, at 3: Supply voltage; 5V up to 36V. Diac Noida January 2, at SunFounder LD is a monolithic integrated, high voltage, high current, 4-channel driver. Enable pin for Motor 2; active mitor. Visit our page for more information. I got such a good information on this topic its very interesting one. Engineers Garage is a community of Electronics and Electrical Engineers where they can take ideas for there projects or submit there tutorials also.

You will learn about different Arduino Project l239f which are used in our day to day life. On the rising edge, data in the shift register moves into memory register.

L293D DC Motor Driver Module

Enable Pin is use to ena b le or to ma k e a chan n e l active. This high-density System-in-Package SiP integrates controller, power switches, and support components. Enable pin for Motor 1; active high.

LD is a 16 pin IC having two enables pins which should motoor be remain high to enable both the H-bridges.


This higher current signal is used to drive the motors. Thus we insert m o tor driver in between m o tor and m icrocontroller. Supp l y voltage Vss is t h e Voltage at which we wish to drive the m o tor.


I’m new with all this thing. Does the output from LD control the speed of the motor?? Input2 for Motor 1. Vedavyas July 28, at 1: Diac Noida May 2, at Kranthi kumar June 13, at 4: I never seen motod type of post. Or does it only decide id the motor runs in clockwise or anticlockwise direction?? With the proper data inputs, each pair of drivers forms a full-H or bridge reversible drive suitable for solenoid or motor applications.

This post are really helpful for those who have big fan of Plane. Unknown April 10, at 7: It’s very beneficial for all the electronics and electrical engineers community.

Time sequence input of shift register. Unknown July 14, at 3:
