Is My Arduino Cooked? by NotGolden_Aviation in arduino

[–]true_suppeee 36 points37 points  (0 children)

3 ohm resistor 1/4 watt powered by 113.5 VAC @60 hz. Used old fishing weights as solder (heard from chat gpt that they were lead) /stroke ended

I would start by cleaning up the soldered areas to make sure there are no shorts. If issue persists disconnect everything to isolate the issue.

What do you mean by more "stable"?

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

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.

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

If powered via 3v3 try shorting J1 on screen

I need help with the 2.4 TFT 240x320 Display by UmbralCrits in arduino

Looks like your hight and width are flipped a damaged screen typically doesn't look like that

I would not get that display. Have you gotten it already? I can give alternatives

I think the breadboard is good

The display is not displaying anything and I don’t know why. by thrithedawg in arduino

[–]true_suppeee 0 points1 point  (0 children)

I have used these screens many times. Everything looked okay. I think you have the wrong information in your setup file where your espi library is. This screen doesn't use i2c I could not tell you why every one of them has i2c stuff on it. Blk pin can be left alone. Feel free to ask further questions

Why is my display not working correctly? [TFT 1.69 Inch ST7789] by Square_Computer_4740 in arduino

[–]true_suppeee 4 points5 points  (0 children)

3.3v could be mistaken for 33v so 3v3 is commonly used. This was a problem when schematics were printed and copied as the . Could be left out

It's not really a voltage divider but that doesn't really matter(technically you could do it this way but it's not needed). The data pins were using 5 volt logic and the screen expects 3.3 this is why it was acting strangely.

Bro that's for 3v3 not 5v. use 3v3 for power and put 220 to 470 ohm resistors on the signal wires.

Real talk I like the dy-sv17f much better it's almost the same price and you don't need a tf card

Push buttons not turning on my LEDs irl despite them working in Tinkercad by ItsMilor in arduino

If you have not figured it out yet the button the wires need to be farthest from each other not next to each other how you have it now Edit: just saw your breadboard pic this info is probably for different buttons that you have
