I just lost 5 hours figuring out what I did wrong... turns out it's bad contacts in that shitty breadboard! UART communications seem to be very sensitive to bad contacts...
I don't know what is wrong with my circuit, but if I touch certain components it will suddenly work. At this point I think it is the breadboard, I'm using the small one that came with the arduino. Probably cheap crap. Maybe I'll just soldier everything together to rule out the circuit design, which I am basically just copying from online
It's almost certainly a bad connection either from really skinny component leads or a bad breadboard. If it came from the real Arduino folks at Arduino.cc it's bound to be a high-quality breadboard though. It's also possible you have a bad component. And even less likely but possible, the capacitance of your body is triggering a sensitive component. But probably just a loose connection somewhere. Soldering everything is always a more secure way of doing it. Use perfboard for that. Here's a pretty good video if you're not familiar with perfboard: th-cam.com/video/l9Kbr8cPqOE/w-d-xo.html
Is your arduino authentic, or a knockoff variant purchased elsewhere, like Amazon? I also had bad luck with those breadboards when I started. Pushing components seemed to be necessary to get proper flow because of the terrible wiring.
Correct about, my vintage 3m fancy board, is better than anything else I own, the one the came with my Bell & howell console 80 is also great, The one with my arduino kit, is crap!! By the way great videos.
The wrong solderless breadboards can be difficult, or impossible to work with -- I show you why.
The photos on Amazon have NO relationship to the product you receive. Amazon must remove unscrupulous sellers.
Nice. Thank you. I'll watch out for those when next I'm shopping for boards.

Yeah I hear you! It's great to get inexpensive products from China but those defective knock-offs can sure ruin a guy's day!
Elegoo isn't an Elenco knockoff. They make decent stuff, I've bought a number of their products and have never had an issue with them.

Excellent info. Thanks!

Yo pensaba que en esos orificios , ivan solo integrados.❤😂
Cheap Chinese rip-offs.
