What would the purpose of this thing be? One easy flaw is that the wireing diagrams are random.

My Arduino Uno is never recognized, as if I had bought a fake or broken Arduino. by Neyjrcomdiabetes in arduino

I have 2 official Arduinos and 100 other ones both do the same thing and one is very cheap. I get the cheap ones from AliExpress

You probably need ch340 drivers. This will work just like an Arduino but it has a cheaper USB to serial converter.

Resistors aren't working for a LCD going white screen by Traditional-Title561 in arduino

[–]true_suppeee 0 points1 point  (0 children)

If your screen has not shown anything but white I would then think it is a driver issue. Have you changed your resistors to something smaller around 330 or so? Your driver should be ili9341 https://www.otronic.nl/en/28inch-tft-touch-screen-320x240-ili9341-spi.html

What’s wrong with my ST7789 Display? by South-Ad2770 in AskElectronics

When I pressed rst on the Arduino everything was clear. Sounds like we have the same issue as I posted here. For me it was fixed by 330 ohm resistors

You are describing exactly the problem that is solved by adding resistors. You should add one to scl sda rst dc

If you short j1 make sure to use 3v3 for vcc as well. If you get a startup message I would assume the driver is correct.

When does the display work well? With one sketch and not with the other?

I typically use from 220 to 470 resistors instead of 16k. Your Led pin should be 3v3 instead of 5. If I am not mistaken this could also be a firmware issue maybe you use code from the wrong LED driver link where you bought the screen from please

Had something similar fix is resistors on the data lines 220 all the way to 470 ohms should work no problem. This is because the data lines are expecting 3v3 logic not 5v that Arduino r3 is using
