L9110 with Arduino Code – Part 2: How to Control Linear Actuators

L9110 with Arduino Code – Part 2: How to Control Linear Actuators
In this tutorial I will show you how to use the L9110 motor control board and write simple Arduino code (see code below) to control various types of motors in your own personal projects. The L9110 is a compact and inexpensive H bridge motor control board that easily interfaces with microcontrollers such as the Arduino or Raspberry Pi.

This board can be used to control two small DC motors simultaneously or can be used to control a small stepper motor, such as a NEMA 17. The board operates between 2.5- and 12-volts DC. It is capable of sourcing 800 mA per phase sustained and 1.5 Amps momentarily.

This tutorial is divided into 3 videos. Part 1 covers the speed and direction control of DC motors. Part 2 discusses the control of linear actuators. Part 3 demonstrates how to control the speed and direction of stepper motors. Each video includes step-by-step set-up instructions as well as basic Arduino coding that can be incorporated into your own projects.

Thank you for posting this. Seriously… I’ve been searching for this exact subject.

I was glad to have added a sketch of all the connections including the power supply

I cannot tell you how much at ease you have put my mind to with this explanation! Absolutely love it! May you advise as to how a light source tracking PCB board is connected and coded to a linear actuator? The goal is to create a solar tracking system and I'm familiar with the linear actuator, just not how the connection and coding to the sun tracker and arduino works.

I like your videos and I think you got a lot to teach, so I subscribed, but please try to avoid asking people to subscribe so often!! maybe once in each video would be fine but some of your videos are like 20% references to other videos / asking people to subscribe!!
Good luck and thanks for the video :)

Great Video! I am also at looking to control a linear actuator with a joystick, with the actuator returning to 0 once the Joystick is released (neutral position) I know it’s possible, just wondering how to set it up? Thanks in advance

[Randy]

Great video! I am fairly new to ardunios and found your video because I am looking for a tutorial on how to use a arduino with a linear actuator using one switch. Turn on the switch actuator goes full out and stops and then turn off the switch and actuator goes full in or home.

Also would like to see a stepper motor do the samething. One switch controls actuator out then turn off and actuator goes in. Could you please do a video on these? Thank you sir I appreciate you taking the time to help noobs out like me 😁

Hi, Just found your channel. I am looking for a way to use an arduino to make an actuator return to it's
half way out or half way in position when power is released from a joystick. Would love to see a video on this setup. Regards, AJ.

[jaandel]

It will great have it to extend to certain height when its activates o power it and stop when touch the magnet automatically

[electricalcoder]

Wow....great work dude....your projects are awesome....iam also...making...projects in...my channel...too dude..

[dbhujel]

How can I achieve the opposite behavior of my current setup? Right now, when a magnet approaches the sensor, the actuator fully extends, and when the magnet moves away, the actuator retracts. I want the actuator to retract when the magnet is close and extend when it's away. Could you provide some advice on how to accomplish this?

[Mr.GS-]

Great demonstration! was doing research for a project I’m about to get my hands into and this is exactly what I needed 😊.

Btw, if I was to say, use two actuators to move two flaps, in two different directions, I will need two proximity sensors I’m assuming? In which case my next question would be, can I wire two sensors in Parallel to the pins used in this vid? Or the board has an option for two sensors.

[mpmccurry]

Could you use a laser tripwire in place of the magnetic sensor to activate the linear actuator?

[Zero_point]

I’m interested in learning about a linear sequence of events such as when one actuator has finished its given action another starts a given action and then reverse the process

I have been on the lookout for something like this, I want to get a robot vacuum cleaner and hide the docking station under a drawer or something similar, then id like to have a lid to open and close for the vacuumcleaner to get out from. (I 'll let the lid stay open while the cleaner is doing its thing so that I can keep it simple and just control the lid with am initiator/sensor as you have done here) The only thing is that I think the actuator would move too slowly for the vacuum so that it'll crash before its fully open. I know you powered your cylinder with 6V, I wonder if I'll have to power my cylinder with 9V or 12V to see if that would solve my problem, do you have any suggestions or ideas? (I havent bought anything or started this project yet, this is purely wishful thinking and planning)
Thanks

Hi,
Thanks a lot, its really greate effort and great knowledge.
i need to do a project for a preset position linear actuator with a DC motor abd a stepper motor, with Arduino Mega or UNO but i am not able to write the code and the scheme, can you please help.
Regards

Hi! Hobbyist here, was wondering why when I received my L9110 that it didn't work with my 12VDC actuator and my adapter/power supply but I see now that you are working with a voltage-box etc and ramping down power to meet the ampage limits of your driver (still a little puzzled how the motor inside the actuator is running on half the voltage, but I digress).

Since I don't have a 6v power supply is there any recreation of this with the L298N and a two wired actuator for the same kind of directional and speed control with 12VDC. Or might I be better off using a relay to do the same functions achieved here? Thanks!

[Danztheeman]

I want to be able to open and close with a remote control, a flip top cabinet door that houses my split system AC/heater. I guess the best way to do that is with a linear actuator. Not sure where to buy the necessary parts. Any ideas?

[kipingky]

Super useful video, thank you Sir....please if possible make video to control speed and direction of 3 phase AC motor using arduino...thanks

[xAckarax]

My actuator extended but it did not retract after I reverse the connections. Do the power supply have to support reverse polarity?

[BlkDrPhill]

Hi, I am wondering if you are able to help me with a assignment i am working. it is very similiar to this project except i am attempting to use a load cell to move the actuator. i.e. have the actuator move when weight is removed from the load cell
