how does UART work??? (explained clearly)

UART is one of the many ways that computers communicate with each other. In this video I explain how UART transmission works. It all comes down to how voltages represent bits that make up binary data. In my demonstration I am using an Arduino board to generate The data signal and a RIGOL DS 1102E oscilloscope to visualize that signal. Comments, questions, and concerns are welcome. Thanks for watching!

bit-by-bit, this video adds to my understanding of UARTS... thanks

Well done. I'm a old timer in electronics but never got into computers. Now that I'm playing catch up I'm having a hard time finding a place to go for good explanation of things. You did a great job. Keep it up

This is a perfect explanation of UART and I like how you covered baud rate and the fact that it transmits by LSB first.

I know its been 7 years but this is a great video :D
Thanks for posting it !

Thank you. Very good explanation and nice to see visualization of the binary representation of O.

You have no idea how much just cleared up in my head. Usually when I watch the video I’m like, “yeah but why?” Thank you for explaining EVERYTHING

Great starting point for those looking to understand UART without going into math. I’m sure this video will continue to be useful for sometime to come. 👍 from me! 🇬🇧

I have experimented with my Arduino and with oscilloscope device is really fascinating what we can do! I made my own code for communicating with my computer (very easy) and it works! People even don;t think that there are thousands of possibilities and only open mind is needed for ideas! People seem to be like sheeps. One man invents something and then everybody uses it but withut realising that there is not only one solution or way how to do it and how to communicate, send/ receive signals etc. Just my own reflection ;)

Great!! Simple and clear, without not unnecessary details!

[strauss]

Thanks a lot! That's what I call "clear explanation".

[paramhansnabar]

O wow 😂😂. No seriously this is the best explanation about data transmission. Thanks for making this video

This is ace! I’ve used comms for years between devices, and taken that it’s always worked. Setup the correct comms settings and away it goes. but I’m now at a stage where I’ve got to take comms signal from an old device and manipulate it to deliver something readable. This has helped me understand how it is sent and received. Knowing this gives me some idea how to move forward from here. Thanks!

Huge thumbs up. Your video explains what the greedy colleges of mine on a job I left didn't want to explain to me. A huge thumbs up for your job!

[burlapjack]

Thank you for making this video. Dummies like me usually have a hard time with concepts like this. I appreciate your thorough explanation.

I'm watching your video to help me review/understand UART before diving into learning how to use it on a dsPIC33.

But I notice quite clearly that you're left-handed. I am not, but my dad is. It is a foreign world to me. My dad may still have his left hander's coffee mug, which has a hole on one side (and thus a limit to how much you can fill it), restricting it to be used with the left hand. Right handers will spill coffee on themselves with it unless they awkwardly try to cover the hole with their lower lip.

Top work mate. I am a sparky and am familiar with a lot of concepts but UART is not one. This is a great explanation.

[danyjoe]

Watched this today for my exam, helped a lot in understanding how UART actually works, thanks a bunch

[felixgspandl]

Thx man you really helped me with my school presentation

[alpyldrm]

Thanks for that. It was pretty smooth way to explain UART.

That's about the clearest I've ever had anything explained to me. You've earned a subscriber.
