I've wired up my Arduino Uno board with this screen: PiTFT Plus Assembled 320x240 2.8 TFT + Resistive Touchscreen : ID 2298 : $34.95 : Adafruit Industries, Unique & fun DIY electronics and kits. I am using this code: GitHub - adafruit/Adafruit_STMPE610: Arduino library for STMPE610/811 resistive touch screen controllers. I attached some photos of my setup. I hope it's not too dificult to see the wiring. Does anyone have any idea on how to solve this. I've been sitting with this a few days without finding a solution.

Edit: The site crashed each time I uploaded the images. I don't know how to fix that
