Linear actuators are essential components in the realm of mechatronics and robotics, seamlessly combining the precision of Arduino microcontrollers, the power of DC motors, and the interdisciplinary field of mechatronics. These versatile devices play a pivotal role in converting rotational motion into linear motion, providing controlled and programmable movement in various applications.
At the heart of linear actuators lies the synergy with Arduino, an open-source electronics platform widely employed for its flexibility and ease of use. By interfacing with Arduino, linear actuators enable precise control and automation, allowing users to program intricate movements, adjust positions, and respond dynamically to external stimuli.
The integration of DC motors enhances the functionality of linear actuators, offering a potent source of rotational power. The combination of Arduino and DC motors facilitates not only straightforward linear motion but also the ability to implement complex motion profiles, ensuring smooth and accurate operation in mechatronic systems. The programmability of Arduino enables users to customize the actuator's behavior, making it adaptable to a diverse array of applications in robotics and automation.
Mechatronics, the interdisciplinary field merging mechanical engineering, electronics, computer science, and control engineering, plays a fundamental role in the development and optimization of linear actuators. Engineers and designers leverage mechatronics principles to enhance the overall performance, efficiency, and reliability of linear actuators, resulting in advanced solutions that seamlessly blend mechanical and electronic components.
In robotics, linear actuators serve as indispensable components for achieving precise and controlled movements in robotic systems. Whether it's in the joints of robotic arms, the adjustment of grippers, or the positioning of sensors, linear actuators contribute to the dynamic and coordinated motion required for successful robotic operations. The marriage of Arduino, DC motors, and mechatronics in linear actuators exemplifies the intersection of technology and engineering, offering a powerful and adaptable solution for a wide range of applications in the evolving landscape of robotics and automation.

Thanks, great example of how you can make your own things as simple as possible. Keep it up!
Thank you✨really appreciate your comment
This was really helpful for one of my university project 🤩 keep posting good content 🙌
Thanks for the comment
very interesting .it was extremely well thought out . my only question is how the top and bottom limit is achieved. does it automatically stop at full reach and automatically reverse ,because of the type of motor you are using . thanks
Thanks for the comment. This version doesn’t work automatically that means we should keep our attention and we should stop at top and bottom limit by ourselves. But I have developed a second version that stops at both ends automatically. You can watch it:

Thanks✨
your video showed how the screw stopped where you marked the
tube with the felt tip pen - in and out. When you made the marks,
you turned the screw until it stopped then backed the screw off
(unscrewed) about two turns so as not to stall the motor.
So far so good, standard practice.
BUT - since you did not use limit switches
how did you make it stop at the lines you made on the tube?
Without limit switches, the screw would turn to the end and stall
the motor.
I hope that helps you understand so you can describe how you did it.
OR, did you stop the motor manually? That is, switch it off then reverse?

Yes, I stopped the motors manually.
thank for your comment. Sorry for any misunderstanding.
Hilarious. I built the exact same linear actuator with the exact same yellow motor last year. 😀 The only difference is: Instead of the smooth yellow coupling you used, and then you heated and smushed onto the threads, I made a coupling with a hex socket. I put a nut on the rod, and used the Red color (permanent) lock-tite to affix ("weld" as lock-tite would call it) the nut onto the threads, and essentially created a really long bolt which is turned by my custom plastic socket.
Pleasure to ask it. Actually, it is a good method. Unfortunately, I tried the same way using a nut, but I can't achieve a smooth motion. (Check this out: th-cam.com/video/EXgNzbWiBSA/w-d-xo.html) So I chose this way.
nice job, but I am confused how you made it stop at your marks on the tube.
I noticed you came to end of threads and backed it off a turn or 2 so as not
to stall the motor.
I'm unable to understand what you mean. Could you please explain again?
Don't ike the DING-DING bell and Fake Voice while watching....
