Arduino Tutorial 30: Understanding and Using Servos in Projects

You guys can help me out over at Patreon, and that will help me keep my gear updated, and help me keep this quality content coming:

In this lesson we learn how to control a servo from the arduino, and how to incorporate servos into our arduino projects. We will show how to program, control and build projects.

You can get the kit I am using for this series at the following link:

Also, you can get nicer servos than the ones in the Elegoo kit here. These are the good ones I use in most of my projects.

Follow along on our WEB site:

When I graduated, I'm going to give a big shoutout to PAUL MCWHORTER!!

man, if you read this comment, I am inspired by people like you who does not charge for learning. Complete role model

The delivery on the vodka joke was a work of art. Well done, Sir.

Thanks for the excellent lessons, BTW

That awesome feeling when you're actually excited about homework!

I had a difficult time with the servo wanting to return to the 0' position after the position was entered. At first the servo would hold position with the simple code, but once the serial monitoring was introduced it would first go to the "asked position" then return to 0' position. After doing extensive trouble shooting with codes and GTS-ing the issue, the solution was simply selecting "No line ending" on the serial monitor.

Upon successfully trouble shooting this, the homework was a piece of cake. I love the math (finally understanding dependent vs independent variables when graphing them. Thank you Paul for the amazing lesions and topics!

47 seconds in. I am subscribing. This guy is too real.

I like the fact that I can watch a whole tutorial without commercial breaks.

Anyone else feel sad when you have to disassemble a previous project to continue learning? A small price to pay for salvation...

Not having any background in this field, I started at tutorial 1 and played along bit by bit; making sure I understood everything before moving on. I surprised myself when I actually pulled this assignment off with ease. It pays to keep good notes, but mostly, it pays to have a teacher that knows how to teach. Many thanks Paul...

Hello Paul and everyone,

I have been following along with the lessons and have been thoroughly enjoying the series so far. Thank you for taking the time to put these videos together. I have completed all lessons so far. I got this assignement to work very nicely with the photo sensor.

If anyone was wondering, I'm 36, and still do my homework, lol.

Thanks again!

Hi Paul, I am teacher at Boshoek Primary School in South Africa (Rustenburg) teaching Coding and Robotics Grade 4 to Grade 7. You are really inspiring us to disseminate your knowledge and skills to learners. Thank you so much.

I did my homework. It worked! I have not ever done homework ever, not in school, never. Only in your course, Paul!

[chrisingram]

Good Evening Paul, now that I've finished binge watching your videos and have seven days to finish the homework assignment, it's interesting to see that your other students are also going out and researching the current assignment. Several others have noted in the comments about the map() function that is found deep in the servo instructions on the arduino site, it goes to show how well we are all taking your assignments to task. Thanks for keeping us all thinking and learning.

I succeeded in doing your homework. I am following you since the beginning. Thank you for sharing your skills and passion. Your structured way of explaining things does not only teach us a lot about Arduino, but also in addressing other little challenges in electronics and IT. -- A Belgian guy in London.

The homework is where I have really set the things you've taught me! I am always excited for the homework. I like that you come up with the idea and then I need to make it real. Thank you, Paul!

This is the best Arduino tutorial around. Mr. McWhorter not only teaches how to use the electronic. The huge bonus is coding through a systematic, stepwise approach that helps get acquainted with commands and syntax. I am so grateful I finally discovered this treasure in the YouTube haystack.

I know it's been 3 years since these lessons were posted, but I'm a Newby to Arduino. I enjoy the little successes , like seeing the servo motor moving for the first time. Thanks Paul for these awesome lessons. 👍

[caripatd]

I did it on my own and It works. Thank you Professor McWhorter, so far I've been able to do every homework without the answer, except for the push-up button, that one really got me. Really good teaching method. I'm a mechanical engineer with a desire to learn mechatronics. You've become one of my favorite teachers in all my student career. Appreciated.

Hello Paul, I know I am watching your tutorials a time later, however, I did do your homework assignment with the servo/ photo resistor and with some thought, trial and error, I was able to move the servo 90 degrees back and forth depending on the light conditions. What a rewarding feeling. Thanks.
