Lesson 98: Arduino 10 LED Push button Projects, Potentiometer LED Voltmeter and Traffic Light

In this lesson we learn how to use LED and Push button in this 10 LED projects. Wiring diagram is shown, code is fully explained and demonstrated with multiple change of settings for each project. We read potentiometer's voltage and display voltage by turning each LED on to represent voltages. A Simple traffic light project.

Projects list:
1-LED ON OFF
2-LED ON/OFF with push button
3-LED ON/OFF toggle with push button
4-Fading light of LED
5-Fading light of LED using push button
6-See Saw with LED
7-Walking Light
8-Walking light with push button
9-LED voltage level meter
10- Arduino Traffic Light

Thanks so much 🙏 👌. There are so many Arduino tutorials on YT, yet only a very few are really taking the time to explain what should be the very first basics to anyone's willing to write his own programs, by giving simple tricks as theses ! Bravo from France ;-)❤️

Great explanation! You are quite fast in explaining and advancing but for me (and my basic knowledge) it is just the right speed, I really like to follow you along, perfect timing ;-)

thank you so much its a super helpful video!!!🙏🏻

I want to do #8 to make walking led but have an option to go forwards or backwards. Ty

Hello sir good day ! tysm for your nonstop uploading tutorials. I woud like to know if there is sequence in traffic signals like it will turn RED, RED AND AMBER TOGETHER, GREEN, AMBER AND THEN BACK TO RED my activity is so hard. It need push button and if we hold the push button down, the lights will change in sequence by themselves with a delay between each steps. I am hoping for your response. Thank you so much sir ! more tutorials to come !

Sir we need program push button for 2 led
Push button 1 led low light
Push button 1 led full light
Push button 1 led blinkin
Push butoon 1 led off 2nd led on
Push button 2 nd light off
