There are a couple of concerns here. Motor drivers typically have what is called a truth table that determines the effect of its inputs. You can always change the direction of a motor by reversing its wiring. Powered by WordPress and Hybrid by Bajdi. Hi Soundguy66, Shutdown start as soon as I start the motors. With a maximum peak current of 1.

Each set of screw terminals is used to connect a motor.

Welcome visitor you can login or create l91110 account. It seems to be designed to be used in toys and small robots. I looked for a simple module with an H-bridge type of power driver. So maybe you can help: Thank you very very much!!!!! Here is the sketch to test the module with 2 small DC motors:.

L H-bridge module |

Hi Lefty, I checked the current draw of the motors and it was some where between. When the sketch first runs the motor is still. This is why some of you are frying the ICs, sorry. The IC will handle the resulting intermittent back EMF generated motlr the motor is just used run forward, stop, run backwards, etc.


Press the button and the motor rotates, press it again and motpr motor stops for a brief moment then rotates in the opposite direction. PWM can be used to drive the motor at variable speed in either direction and this is what the sketch here does.

This is the input voltage for the L chips.

L9110S Dual-Channel H-Bridge Motor Driver Module

motoor By continuing to use this website, you agree to their use. I bought another o9110 motor driver, this time a module with 2 L H-bridge chips. The truth table for a single HG L chip is as follows: You only have to supply it one voltage between 2. Note that the actual direction of “forward” and “reverse” depends on how the motors are mounted and wired. More then enough for a small DC motor. This would reset your motors. On the third press the motor stops.

The truth table for a single HG L chip is as follows:.

Do you think it would be possible to control this driver with a joystick? Same thing for motor B. It looks from the data sheet L110 need some sort of square wave but I am not sure. Choose a higher performance motor driver for more power and control options.


With a maximum peak current of 1. That can be a significant problem. You are commenting using your Facebook account. Can you post connection with battery. Also, depending on your power supply if you are driving the DC motors from a higher voltage than the logic partyou may also want to remove the 4 10K resistors at the bottom of the board, these are pull up connected to VCC.

Thanks for your help In the data sheet it shows a square wave can someone tell me about that? So when pin 3 is sinking it goes one direction and when it is sourcing it goes in the other.

This means that if you are using a 5V chip, you should expect to drive 5V motors. Thank you I almost fried my board do you have a schematic or diagram for this project with IR added also? The HG L is a compact motor driver chip that supports motof voltage range from 2.
