I installed Arduino Uno with paj7620u2 as shown in the picture.

I have a printer like the one in the picture but I couldn’t figure out how to connect it and program it in Arduino Center image description here

What I would like to do is make a esp01 with gpio16(wake) pin broken out using the original esp01(s) design/footprint.
I found this stackoverflow question but it was closed already: /questions/78731991/does-anyone-has-gerber-files-of-esp01

I don’t know why but I am having this message:
“avrdude: stk500_recv(): programmer is not responding”
every time i upload my code in the arduino ide software.
I was making a car with the keyestudio kit and arriving at the end, when I put my code and go for uploading it I get this… The strange thing is that I’ve programmed a 10 lines code for a servo 15 minutes before and I had no problems… please help me guys I am really struggling with this

i have to do this thing
Simulate a matrix keyboard that, in addition to the numbers 0 to 9, contains Add, Subtraction, Clear and Result keys.

i have simple program written for UNO R4 WIFI.

The touchscreen isn’t working correctly on the answer rectangles in my quiz game. Despite proper calibration and threshold settings, touches are not detected accurately on the rectangles. Help with debugging would be appreciated.

Closed 3 days ago.

within the initial testing phase i was using a Elegoo Uno R3 and the code i used for that as well as the electrical circuit worked perfectly. However, i now need to use the Portenta H7 Lite but when i replicate the code and circuit it doesn’t work on the Portenta H7 Lite.
