Fun with Arduino 02 Digital Input Output

We write a sketch that turns the on board LED on when we press a button. We'll use the pinMode, didgitalRead and DigitalWrite commands, as well as an if-then-else.

Appliccable to Uno, Nano and most other Arduino types.

Rudy, what an excellent video, i will continue to watch this series as this is of great interest to me. You are a very good tutor, as you explain things in a very basic layman's terms. well done and thank you!

Rudy....This is a great series and I am working my way through the whole series, Thank you for all the effort it is truly appreciated

As a beginner, in this video I did not completely understand the whole connections, maybe because some connections are handled internally by pullup. I think it could be clearer to have a complete wired connection, but I think you will do that in the next videos. So moving on into the chapter 3. Thanks!!

Hi Rudy, Just want to thank you for your videos. I really like the way you explain everything. I have been working with Arduino for a little while and still felt I was not getting what I needed to really understand what is taking place in the code. You make this very easy to understand. Keep up the great work! I will be following all your videos to have a better understanding of the code. Thanks again !

Just as a second thought or second comment.  Your presentations in terms of the graphics is outstanding.  I  a person could do a whole series just on the way you present the pictures an all.  Thanks again.

If I wanted to push the button and have the LED stay on for a determined amount of time before it shuts off where would I put the delay?? Also is it possible to disable the button durring the time so if it gets pushed again it doesnt restart the time?

Hi,
Thanks a lot, its really greate effort and great knowledge.
i need to do a project for a preset position linear actuator with a DC motor abd a stepper motor, with Arduino Mega or UNO but i am not able to write the code and the scheme, can you please help.
Regards

Hi. Maybe I'm missing something but isn't the program saying if pin 2 is off (switch is not pressed or LOW/OFF) then the LED is HIGH/ON?
