This is the most timely video, I think, that has ever come across my lap!! I'm building a center-articulating 4x4 Cub Cadet tractor and am going to use a linear actuator for the steering. Until this video, I had absolutely NO idea how I was going to do it!! Sweet...THANKS!! What would I do differently if I just have a hall-effect at the end of a steering shaft instead of using a remote control receiver? Thanks again, Bill

@ScienceFunInnovations Год назад

Glad it was helpful. What exactly would you be doing with the hall sensor?

@billbayer5526 Год назад

@@ScienceFunInnovations I will be using it on a lawn tractor I'm building. I actually just posted a video of it last night with the linear actuator mocked up. I will have a steering wheel with a shaft that terminates at a hall effect sensor. If I steer full left, for example, the sensor will go to .5V. Steer full right and it goes to 4.5V. Steering centered and it's at 2.5V. So it's really similar to what you have in your video but instead of using an R/C transmitter, I'll be using a hall effect sensor.

What do you recommend for a on off on switch & has positions setting too? Ie. Im using an on off on switch & actuator to bring down a reverse bucket on my jet ski, i had to adjust the stop inside the actuator. But i need a faster actuator & they are 3" & 4".

@ScienceFunInnovations 2 года назад

Not sure exactly what you are doing, but linear actuators are pretty slow. You may want to use a 1" actuator and a 4:1 lever arm. That would make it travel 4X as fast.

@garysherwood3136 Год назад

What speed actuator do I need for a motion simulator? Trying to decide between a motor or the actuator. Thanks for you video!

@ScienceFunInnovations Год назад

Most actuators are pretty slow, but they do make high speed ones. Mine is only probably 1/2" per second.

@codysimonson6260 10 месяцев назад

I'm in the starting phases of using an OEM wastegate linear actuator and using a PWM signal from an aftermarket engine computer sent to an Arduino. The Arduino will convert those to a pwm signal that will be pushed to either the retract or extend pins of the controller depending on whether the engine is hitting target boost pressure or target actuator position. My question though is, since the original PWM from the engine computer is controlled via PID, do you think its worth it to use the braking function of the motor controller or not? The original PWM will be constantly hanging throught the rev range.

@ScienceFunInnovations 10 месяцев назад

Sounds like the PID will take care of it.

@diegodominguez2785 Год назад

Hi! I am trying to build a close loop feedback system using a linear actuator that is able to maintain a constant force. I am using it to break some polycarbonate specimens that will deform as I apply the load and thus I need it to adjust the force as the specimen deforms. do you have any advice on this matter? thank you in advance!

@ScienceFunInnovations Год назад

I would use a load cell or force sensitive resitor to give the force feedback. If the load is < desired amount, have it extend and if > desired amount, have it retract. Check out some of my other videos which may give you some ideas.

@Ayo04Soul 2 года назад

Hi, how would you go about converting an existing 5 pin wired controller to a wireless remote controller. I need to either replace the wired controller or add a wireless controller to a recliner chair. The chair and wired controller work okay but is I need to control it from the other part of the room. The wired controller can be removed at the (180) 5 pin connect so I think I need a way to read the signals from the wired controller.

@ScienceFunInnovations 2 года назад

Check out my other video where I used a remote control to control a 5 wire actuator.

@hannahreiner344 3 месяца назад

great tutorial! what size wires do you use. I am trying to use a 12 V linear actuator with a current load of 4.5?

@ScienceFunInnovations 3 месяца назад

I use wires that can handle the stall current for the actuator. You will have to look up that value for your actuator and size the wires accordingly.

@mateooliveras910 Год назад

Hey I am working on a project at the moment for solar trackers, Im trying to figure out if I could use a BTS7960 board to control a 2 wire L.A. Have my 4 LDR sensors sent to arduino to command a signal to go directly to the BTS7960. I would not need a 5 wire or neccessarily track positions because that would be derived from the LDRS. Am I thinking of that correctly. Mechanical engineer that is nothing but a novice on EE aspects.

@ScienceFunInnovations Год назад

Absolutely. For a solar tracker you can use 2 wire LA's. I have a solar tracker video using a small dc motor, but LA would react the exact same. Good luck.

@lundebc 2 года назад

Could you do this without a built in potentiometer? Perhaps use logic/counter to reverse for the same time it was on? Will have to play with that idea.

@ScienceFunInnovations 2 года назад

Yes you could. I have several other videos about controlling linear actuators. Hopefully another video later this month as well.

@pietheijn-vo1gt 7 месяцев назад

I did this. It's not very accurate, the difference in the time it takes to reach different stroke positions can be quite significant (it's almost linear, but there are errors, even between going from 0 to 100 multiple times)

@putraadriansyah8082 Год назад

will these linear actuators strong enough to operate clutch fork to work as replacement for hydarulic clutch operating assembly?

@ScienceFunInnovations Год назад

They are very strong, but move pretty slowly. It would depend on how fast you need it to move.

@waizghaffar116 Год назад

Can we read the resistance value in Arduino from code with using any ohm meter if we move the actuator to random position?

@ScienceFunInnovations Год назад

Not sure exactly what you are asking, but yes you should be able to read any position.

@martinengen Год назад

Nice video. I am making a stearing for my outboard electrical engine on my boat with a linear actoator (With position feedback) but vant to use a potentionmeter instead of reciver from controller. can i use the same code for that?

@ScienceFunInnovations Год назад

The code would be very similar. You would just command the linear actuator to go to the same position as the potentiometer. Should be pretty simple.

@SAMJAM1107 4 месяца назад

I have a similar problem as you. Have you created a code that uses a potentiometer?

@sr71Serene 4 месяца назад

Would it be possible to control in the same way a linear rail actuator driven by a stepper motor? To gain high accuracy.

@ScienceFunInnovations 3 месяца назад

Different code and different motor controllers, but yes this could easily be done with stepper motors. Thanks!

I want to rotate the egg tray with a linear actuator in such a way that tray will move from 0 positions to + 45 degrees and from +45 to - 45 degrees. now for that what I need is one linea actuator with motor driver and Arduino? and what linear actuator should I use, I have seen some people using 3 pins actuator please guide me as soon as possible.

@ScienceFunInnovations Год назад

If you are need three positions, you need a 5 wire actuator. If you just want fully retracted or fully extended, you can use a plain actuator.

@harryjosephrequieron7166 Год назад

hey man! great vid, can you have a vid on how to control a linear actuator through an arduino uno automatically? like by using some sensors to make it happen. hope you'll see this! have a great day man!

@ScienceFunInnovations Год назад

I have other linear actuator videos that may help. And I am working on another very soon. Check out my other videos on my channel, they may help.

@sr71Serene 6 месяцев назад

Would it be possible to change actuator speed using PWM based on how fast you move the knob/lever on a remote controller? Actuator speed to be proportional to remote lever speed? Maybe using map(); Thank you!

@ScienceFunInnovations 6 месяцев назад

Yes. I have done that in other of my videos.

Using an Arduino analogue to digital converter. I suppose depending on the length of the actuator. What resolution of distance traveled would i get? As i want to control 4 actuators to run level with each other.. My other option is digital encoded actuators to control height. I know a company that sells a controller that works with opto and hall effect . But despite them sending out a replacement controller. I still have problems . So i have decided to build my own. Mostly to fault find , but Maybe as a final solution . Trying to decide on a module that will work with amp requirements is difecult from youtube videos . As some suggest reducing the voltage will reduce the amps required. This goes against all i know regarding power. ie Watts .

@ScienceFunInnovations 11 месяцев назад

For resulution, divide the stroke length by 1024. Or if you use a 12 bit microcontroller you would divide by 4096. Pretty good resolution. Lowering voltage will lower amps/watts, but will also reduce speed and force. Better to get a stronger motor controller that can handle the full power needs.

@randolphpermejo1285 8 месяцев назад

Hello! I’m trying to connect my L298N to the Arduino and trying to power it with the 5V output. However, the Arduino is not powering up. I also powered it up with the VIN and GND connected to the 12V battery and that powered it up. Now, my problem is is that I can’t get power into the rc transmitter and I can’t get control of the actuator. Any tips? Thank you in advance

@ScienceFunInnovations 8 месяцев назад

Weird, when you power it with 12 V do you get 5V on the output of the L298N? Sounds like the problem might be witht he L298N.

@alexanderdakogoljames2495 7 месяцев назад

How can one use this concept to build a solar tracking system to either push out or retract the linear actuator with respect to a connected temperature sensing device? Can one also, use the L298N(~2A) motor driver together with the linear actuator to tilt the weight of 100Watt solar panel? Please, I need your response and guide to carry out a project.

@ScienceFunInnovations 6 месяцев назад

Check out my other video about my solar tracker. Also, check out my other actuator videos which should answer most of your questions I think.

@ScienceFunInnovations 6 месяцев назад

The L298N will probably work, but I would use a BTS7960 if it were me. They can handle heavy loads.

@rommelsanchez9608 Месяц назад

Hello, I have a question. Do you think that actuator can be used in a homemade motion simulator?

@rommelsanchez9608 Месяц назад

I saw some videos where they use a 12v motor with a potentiometer to tell the arduino what position it is in. I don't know if that actuator can do the same job.

@ScienceFunInnovations 29 дней назад

Some actuators have built in potentiometers. See my other videos on position tracking.

I want to control 7 actuators Is there a board designed to handle 7 actuators at once. I have a joy stick control box that can handle the 7 actuators

@ScienceFunInnovations 2 месяца назад

An Arduino Mega might have enough input/outputs.

@cjn316 2 месяца назад

Can you control it via wired joystick?

@ScienceFunInnovations 2 месяца назад

You could wire a joystick to an Analog Input on the Arduino.

@shewagdhanush1391 Год назад

What happens if you rotate the wheel rapidly back and forth?

@ScienceFunInnovations Год назад

The linear actuator moves very slowly. So it would probably wouldn't move much.

Hi if i use power from l298n my circuit works but if i use separate 5v to pot red and black and arduino red and black the actuator make noises and doest work i am very confused here. I connected red wire of +5 with arduino 5ve and pot red wire same with l298n what is happening here?

@ScienceFunInnovations 6 месяцев назад

You probably need to connect the GND's together so that there is a common reference.

@jahanzaibkhan4018 6 месяцев назад

both adapters are different so connecting ground will make no problem right? @@ScienceFunInnovations
