This is the best video ever. While I was already starting to understand, that explanation really nails it for me. Maybe another video on Pull-down and the pro/cons of Pull-up vs Pull-down will make me even more smart!

[snerble]

so THATS why that resistor is there! back when i still messed with arduinos, i always neglected to put that resistor there because it worked well enough right? no wonder i had super unstable connections. i am definitely subbing to learn more about this stuff!

[gordon]

This is so good. Such a good explanation.

[thomasldeanjr]

After reading and listening to other explanations, you solved it for me in 59 seconds. WOW

[ALXandroATS]

The reset pin of a micro controller usually uses the same concept. A pull up resistor tied to Vcc and a capacitor tied to ground acts as a momentary switch to ensure proper instruction startup when power is applied.

I’m sure you’ll cover this in another video, but some micro controllers have internal pull up and pull down resistors that can be configured.

[stalthyone]

Excellent short explanation on the inner workings of IC’s, short but sweet.

[UndregoGrey]

Thank you this is the first video i found explaining this properly

[tapalmer]

I was never interested in the electronics and breadboard resistor chip end of things but I still find your videos informative and interesting

[itachi]

Absolutely love these videos, it's making me more confident in picking up a hobby.

[gazehound]

This is one of those things that every EE youtuber talks about but none of them ever explain.

[runforitman]

I remember, quite a few years ago, when I first started playing with microcontrollers like arduinos
it took me an incredibly long time to find out about pull up/down resistors
I was always wondering why my buttons etc were so unreliable

[allertschallenberg]

This is exactly what a short should be like!

[okay]

Thank you this was the moost easiest explenation i could find, and this in under 60 seconds.

[drapakdave]

Oooooh. I finally get it now. Thank you!

[vladimirsch.]

Thank you so much I was never able to get the reason for the pull-up resistors before.

[alexanderalvarado]

Lots of microcontrollers have internal pull ups you can enable by writing to a register!

[magicsmokemitlothar]

Great video I Love that you make thèse vidéos for beginners. When I started out with this Hobby i didn't Inderstand this for years.

[williamwell]

Very good explaining thank you very much.
I like to add something, that the microcontroller comes with internal 1k pull-up resistor and by programming you have to choose whatever you want to use it or not

[clodman]

These are an excellent series of videos. Have been binge watching them even though I don't really toy with electronics that much beyond getting and Arduino and running the example scripts. Welp, I might get into it properly now
