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.
I've had a few similar requests, so I will work on a future video for that. I might need to order a few parts, so it may be a little while before I get to it. Thanks for watching!
I am almost certain this is not as simple as you hope. Linear actuators have no FEEDBACK, the just have endstops. the arduino has no idea WHEN it it in the middle, or anywhere along it's axis, so this would probably just be a timed move to an approximate center. I guess to do this you would have to add some form of encoder, or an extra limit switch in the center to provide that feedback.
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
If you are just going to have it go to one end, you could command a retract or extend if the pulse width is less than 1600 and then have it change directions when the pulse width is greater. If you want it to stop somewhere in the middle, that is a bit trickier as you would need position feedback. Hope that helps.
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
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 :)
Thanks for the support and the feedback. It is hard to know as a new TH-camr how much to encourage subscriptions. I think my content is getting better, so hopefully more people subscribe with less persuasion and I can get my channel to a sustainable level. Thanks for watching!

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 😁
Hello good afternoon. I am a handicapper and I want to turn an old Segway into a wheelchair, I have seen designs online and who sells them but they are very expensive so I decided to do my own project. I want to put two actuators as legs, but I don't know if there is a way that when they feel the force, when they touch the ground they will stop. If you can help me I will thank you.
One way would be to put force sensitive resistors (FSR) on the ends of the legs. These can be connected to an Analog input pin on the Arduino to detect the change in force. Another way would be to put a current sensor on the power going to the actuator. The current going to the actuator will increase with the resistive force. If you monitor the current, you should see an increase once the actuators hit the ground. Hopefully this gives you some ideas. Good luck!
Hello again, although I do not know about the subject, I was checking what he suggested to me to use a force sensitive resistors (FSR) for my project although I think after watching some videos that it would take more wiring than using a current sensor on the power going to the actuator, I mean, it would take the FSR to the tip of the kickstand and from there take the force emanating from the Actuator, what do you think? I would like if you were so kind and see in this video at minute 1:19 how the kickstands come out and tell me what do you think they could be using for the mechanics? something similar is what I want, but I can't buy a chair like that. Thanks in advance. Here I leave the link. th-cam.com/video/LefWULvn98Q/w-d-xo.html&ab_channel=NinoSpain
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!
My new favorite controller for linear actuators is the BTS7960. I can handle full 12V and heavy current loads. Works pretty much the same as the L9100, but can handle much more power. I use it in some of my later videos.
@@ScienceFunInnovations Thank you for the reply, yes actually at the same time you replied I found another of your videos where you're using a two-wire linear actuator with a 12v battery, L298N driver, so basically the same setup as me. The coding was where my issue was, it turns out! I was previously following some circuit that used the ENA pin, which you completely bypass in the video, and finally got my Arduino to trigger the actuator with just the two pins. But I will look into BTS7960 in the future.
Definitely. I would connect the tripwire to digital pin 2 or 3 on the Arduino and use an interrupt command to set the mode to extend. Then use the other interrupt channel to retract when a button is pushed, for example. I talk a little about interrupts in my latest video: th-cam.com/video/1Ssh2aTDPGY/w-d-xo.html
Yes, just set both outputs to the same value, such as 0. This would hold it in place. Look for my next video in the next week or two on building a solar tracker. I will discuss this in more detail with example code. Thanks!
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
Are you looking to use the ultrasonic sensor for position feedback or just an event trigger? In my latest video I use an infrared sensor as an event trigger. Are you looking to do something like that with the ultrasonic sensor?
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
Yes. 12V should double the speed. Also consider using a lever where the actuator only moves a few inches, but the other end moves much further. The actuator should have plenty of force.
Both the arduino and motor control board were connected to the 6V power supply. The actuator gets power from the L9110, which gets power from the power supply.
Nice video buddy! I want to make a standing desk using two linear actuators. This is the project I'm inspiring from: th-cam.com/video/EXjR-o5gu2w/w-d-xo.html Using Arduino, I want to tell the linear actuators to lift the table to a certain height (standing position) by pressing one button and then pressing another button to tell them to go to the sitting height position. Which electronic components would I need? I'm kind of a noobie and don't know with certainty where to start... Thanks for being so helpful!
I hope to do a linear actuator position video soon that would show what to do. But using two actuators can be tricky if one is a little faster than the other, your mechanism might bind up.
You would just have to check the current under load is less than 0.8Amps. But check out my other videos where I use stronger motor controllers that work almost the same as the L911.
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
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?
Linear actuator is a good way to go. I have another video showing how to control with an RC controller, and I am working on a video showing how to control and actuator with your phone. Hopefully I get it done this month.
If i ran the linear actuator off a 7- pin rocker switch and i wanted to have a 2 switch controlling the main power it would as a power switch. How would i do that
Hello 👋🏽. So I'm trying to figure out a way to control 4 linear actuators at the same time. I want them to stay closed when there is no secondary 12volt source. When there is an external 12volt trigger I want the actuators to open. And as soon the secondary 12volt source drops I want the actuators to close again. Can you help me achieve this? I'm building a poor man's air brake setup... or better known as active areo. The actuators are connected to a spoiler on my car. I thought I could do this using 3 relays but my eyes go crossed when I try to figure out the wiring 🤣.
Use a BTS 7960 motor controller at the full rated voltage of the actuator. You can also look for high speed actuators since you only need a little force to crush a can.
I'm hoping to to do a simple single phase relay video in a few months. I would love to do a 3-phase, but I don't have 3-phase at home. For that you need a variable frequency drive. Some of those have analog or serial inputs, which can both work with Arduino.
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.
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.
Glad it was helpful. You can connect multiple sensors to the Arduino board. The 5V and GND will be in parallel, but the sensor wires would connect to different pins on the Arduino. These videos may also help: th-cam.com/video/qLltghqVrvI/w-d-xo.html & th-cam.com/video/Vc0LKeh_0FQ/w-d-xo.html

@@ScienceFunInnovations hi I saw that video, I don’t want to push a second button to retract the actuator.
