For newbies, at 7:30 the graphic shows 1024 = 2^10 bytes, in this case it's really 2^10 analog levels (a 0 to 5V analog value divided up into 1024 digital values ranging from 0 to 1023) where in this case the 10-bit output of the Anlog to Digital Converter (ADC) is from binary 0000000000 (0) = 0V, all the way to 1111111111 (1023) = 5V and various level in between. We all make this faux pas in computer science from time to time as we look at the number of bits related to how much memory (bytes) were are addressing, the concept here is scale and is the same in either case.
Great video. Thank you and Digikey for being there for us. I teach Summer STEM in my home. We have very similar teaching techniques. What makes it difficult for me is: I teach 5 year olds at the same time I teach 17 year olds (K-12), but I only take 6 students a summer. I have to teach in a way kindergartens can understand and at the same time not bore 12th graders. But I hand pick students not for their grades but their aptitude and hunger to learn (and help/teach each other). One of my first Math lessons is the Imaginary Number i. It's amazing how 5 year olds can pick up this concept before even being introduced to square roots, let alone negative numbers. Remember 3 - 5 = Can't do? I teach them, can do its a NEGATIVE number: -2. I have to tell my younger students that what they learn in my class is advanced for them and their peers in school, so don't embarrass your teachers or classmates by telling them they are wrong and follow their lessons - they are not wrong, they just don't teach you everything at first so master what they are teaching you at the moment. My students don't address me as Mr. Romsky, it's Paul, Biff (long story), or Romsk. I treat them as young and very young adults.
This is awesome! Still new to this and didn’t know about the pull up resistor through the board. That just solved a problem I was putting off figuring out. THANK YOU!!!
Did you make a video on how to protect your Arduino UNO R3 inputs by using a load resistor and a 5V Zener to limit the voltage at the pins to 5V to prevent blowing out an Ardunio's microcontroller I/O pin if ever driven by more than 5V? Before my students hook up their Arduino UNOs for the first time, I teach them about Zener diodes, how they work, and how to use them in this manner. If a student "blows up a pin" the Arduino is still functional for the most part, but the Arduino's microcontroller is in DIP form and can easily be replaced with a new chip for a couple of dollars,..... hmmmmmm, where could I possibly get Zener diodes, resistors, and new Microcontroller chips? Digikey! Yay! [free plug, smile] This goes for the Arduino DUE as well, but in that case, you use 3.3V Zener diodes because it's I/O is 0V to 3.3V.
Becky, it's great to see you keeping the helpful tips alive over here on Digi-Key!! Keep up the great job
Thank you, provides so much clarity, great instruction.

Thanks for the great video😊
Great video Becky!
Thank you for this
Thank you!!
Thank you.☺️☺️

That digikey nail is nice 😹.. You could paint the schematic symbols of some components you used on the remaining ones 😅..
