Arduino Analog Read - More To It Than You Think

Arduino Analog Read - More To It Than You Think
In this video we look at the simple analogRead Arduino command. We use a potentiometer to simulate input, and finally a little equation to turn our 0-1024 step reading into a voltage.

I will get a small commission and it costs you nothing.

Paul, your videos on this clock are excellent _precisely_ because of the "errors" you made in assembly. It points out the fact that builders need to take care in assembly! But know you this: the clock is dead balls on accurate! Put mine "in service" about the time you made this video and its minutes roll over exactly when the NIST/WWV clock rolls over. I got two of them - red and blue - in the ham shack for local and UTC and they're absolutely in sync!
Thank you for your videos.

Cool. its 5/9/22 and this is about where I am. 1yr into Arduino I have built three Rc cars (Nrf24, Mega328, 6612FNG and generic ESC)on 2S. One 5 channel TX. My problem is I use other folks sketches. I have to work around this. You have my attention.

It's bed time here in Oz - so I'm saving this for when I can sit comfortably tomorrow and enjoy it.

It would be nice to see you read the voltage with a dmm and compare it with the serial monitor. I wonder if it’s exact

[totallyrandomlocksandpicks]

Hey great video, I've used analog read in a similar way to this to control an esc & motor on a test bench years ago. Used serial write as well iirc to talk to the ESC. thanks for the upload.

If you are interested in learning Arduino, I suggest watching this episode on something bigger than a smartphone.
Thanks for the Great Video
Paul 👍
God Bless.

Good stuff Paul. One more piece of information going into the information arsenal!

[madsbaadsgaard]

Great video!!👍 Maybe you should put something in your code to restart the readings every time you run the code. I can see in your terminal program that you’re gartering a huge amount of data. Using a refresh/return(0) might be a better way so that the readings don’t take to much space. Otherwise great demonstration. I’ve learned a lot from you over the time👍

i've used analog pins as an audio input for a "spectrum analyser " prohect and it work but audio signal must be <<5v

[irgski]

What is different if you want to use an analog pin for digital input or output?

[ysfherdem]

no more than i think but very good video :)

[rainfallen]

It's more fun to learn programming in assembly

[educationaltechnology]

what I've learnt is that high and low is not an exact voltage like low means something lower than 1v and high means anything higher than 4v

[meesiphht]

Maybe you should go into a little at the end of what this is used for is real life applications.

I'll let Quincy produce the software. ☮

As much as I want to learn about Arduino stuff, and electronics in general, this video is useless to me as I am only 2 days into learning Python, which from my understanding, the Arduino IDE is written in C++, which for all intents and purposes, means to use the Arduino boards you also have to know C++ programming. So there goes my interest in Arduino. Time to focus on my other interests.
