Arduino Workshop - Chapter Two - Using Digital Pins

In this section, we'll learn how to use the digital pins to read inputs and control outputs.

I have struggled with arduino for years
Well done, your course content has been excellent, well structured, easy to follow
Thank you

This is one of the most well formatted and comprehensive technical instructional video sets I've ever laid eyes on. The instructor is very gifted for capturing attention and presenting content. I have five daughters one is interested in code and electronics. She's only 10 and I have trouble presenting what I know (I repair process instrumentation and automation). She has picked up so much since watching these lessons. Thank you my friend. Absolutely well done!

I'm so glad I found your clear tutorials! I had no idea about the internal resistor on the uno until today lol.

you are the best arduino teacher ive fount on all my years trying to figure out arduino thx

Would it be more energy efficient if when the button is not pressed, then the circuit is open, and while the button is pressed the circuit is closed.
I am guessing that is a different type of button?

Question : @9:25 he created the variable inside the void loop, why did he not declare this variable at the top with the others? Is this then a "local" variable and not a "global" variable ?

Thanks so much for your excellent video. I learned a lot and it was very simple. I'm excited about learning more.

Wish you should show how you wire it up

[joshkrispy]

This was so helpful Thank you so much

[karvasika]

Thank you for the really clear tutorials, starting with my first circuits and I was very glad to find this kind of tutorial that explains all the stuff well.

I have one questions: when I push the button on pin 2, doesn't that become a short circuit because pin 2 is then directly connected to ground? Or what prevents the currency from heating up the wire and destroying the device when the button is pressed down?

How to deal with high or low at power on?

[SouboGaming]

i have copied everything from building the circuit to writing the code and this just wont work, can anyone help?

[marklesterburgos]

is input pullup only applicable to active low logic programs?

[maazshahid]

I have a question, the button is connected to pin 2 and ground while the led is connected to pin 3 and ground, then why does the led switches off when it is pressed. Please help

I am really enjoying this series. I do have a question though. Is there a way to use multiple buttons combinations to create a single action. Like button1=high button2=high button3=low moves 4 servos to one set of position. Then pressing button1=low button2=high button 3 =high and servos change to a different position.

Hello! I would like to ask a question. What happens if I give to the LED pin the opposite reading of the button pin through the code?

[ferbrahert]

yeah very cool I'm going to watch this again and again to understand the breadboard and its correlation with our designed schematic cuz I'm dumb

[wasifalam]

how the pin 2 is connected to 5 volts?

Hi... have been enjoy your tutorial videos they have been a great help in my understanding of Arduino coding. I would like to ask if a 'Pull Up' Resistor should be used if the sketch is to be loaded to a ATtiny or ATMega IC or can one safely use the "INPUT_PULLUP" (mins. 4:10 - 7:29) in a Arduino Sketch. Thank you and keep up the great tutorials.

This means that when your button is off the bulb glows and if the button is on the bulb dosent glow
