Arduino Tutorial 13: Understanding Arduino If Statements

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

In this lesson we investigate use of IF statements in a practical arduino project example. We will read a voltage from a potentiometer, and then turn an LED on if the voltage is above 4 volts. We will learn the different conditional commands in the IF statement.

You can get the following Elegoo kit, to follow these lessons and play along at home

You can get more great arduino content on our WEB site. Link to this lesson:

I am a 70 year old retired electronics tech. I am thoroughly enjoying this series. I build every circuit and write the code. Thank you for doing this.

Hey Paul,
You are not talking to a wall, I am following every single step carefully and I complete all your assignments. Thanks for introducing us to Arduino in such a simple way and that too free of cost. Your selfless efforts will always be noticed. Thank You Sir.

Hi Paul, you are one of the few YouTubers that is a quality educator!! Thanks so much!!

[rajkalex]

Over three years later and you're still being heard. Thank you so much for being a great teacher. On to lesson 14!

Hi Paul, please keep these videos coming. I'm an 81 year old beginner in the UK and I'm enjoying your lessons and actually learning. I love and need your emphasis on the important points and their repetition as it slowly sinks in. Thanks again.

Hi, Paul.I am 80 years old. I have worked with computers and electronics almost all my life. I have also served as a "tentmaker" minister all my life. I have been retired for almost 20yrs and wanted a hobby that would stimulate my mind. I settled on the Raspberry Pi and the Arduino. I already understand the electronics and can program in ASM, BASIC, FORTRAN, C++, and Python. I am still going through each lesson because I enjoy your style of teaching. Thanks for continuing to stimulate my mind.

I'm 21 electronic engineering student and I'm enjoying the tutorials. I have covered the previous 11 Lessons and am determined to go through the whole Playlist!

3 years later and still not talking to a wall! I am taking notes throughout each of your lessons and playing around with the assignments. You are a fantastic teacher. I work with children and want to teach myself and them about circuitry/robotics. I have experience working with web design but this course is by far the most fun I’ve had with anything programming/computer related. The tactile part of circuitry is really gratifying, and your way of slowing down to REALLY explain some of the physics is awesome.

I am 14 years old and I am learning programing from your lecture thank you stay blessed

[MechElec]

I am a mechanical engineer who really enjoys these videos that you have created for the Arduino. Thank you for all the work that you have put into them. I especially like the circuit analysis inclusion. It is good to get a refresher on those details after having such a long period in which I had not used them. I am building all the circuits described and "enhancing" the "homework" that you recommend. Thank you so much, Paul!

I am a 77 year old retired US Navy Missile Technician Chief Petty Officer. Served on four FBM submarines. Just started dabbling in Arduino. Looked at a lot of YouTubers trying to explain Arduino. Most not cutting it in my book. Your approach to teaching the "voodoo" involved in making an Arduino work is excellent. The "Old Guy" is actually starting to learn some of the "voodoo". Just finished lesson 13. Great work. Looking forward to the rest . . . .

[MrGotickiller]

I just finished my Computer Science degree with specialization in Data Science. A friend who teaches Arduino classes in High School told me about the wonders of Arduino Microcontrollers. I found your tutorials on Youtube and This is my hobby for the Summer. I never fast forward any part of your videos even though I am proficient in C++ and Computer Engineering, because your pedagogy is just mesmerizing ! Congratulations Paul for your course, you really are a hidden gem in the world of teaching Basic Computer Science courses.

"AH! HAPPY HAPPY BOOM!" from now on, I'll be saying this each time I succeed in anything.

[garywilliams]

I’m a 55 year old mechanical/hydraulic engineer, I do all the circuits, code and homework. I’m loving these tutorials! I have some uses for the Arduino to integrate into my home automation setup, I could just copy and paste other people’s projects from the internet but I really want to learn how to do it myself and these tutorials are excellent. Please keep up the good work!

[stanwetmore]

You are not just "talking to the wall" as you put it. I am listening and doing the assignments that you suggest each time. I love it. The home work is not too hard. Keep up the good work.

[michaelgrahamjr-be]

I 'm just getting started with Arduino and couldn't of asked for a better teacher. Your tutorials have helped out tremendously. Thank you very much.

[xAudio]

I love how satisfied you get when simple programmes works even still after years of doing this.

[MarvelBi]

Senior in high school. This series has mind blown me with the amount of knowledge you make easier to understand for about anyone thank you. I have had very little to no confusion this far

[jd]

Hi Paul, I'm newish to Arduino and new to your videos. Love the format and I do build the circuits. I also do the homework. It's great that you do not edit out mistakes from the lessons. Great way to learn debug processes.
