Be gentle lol
fairly new to this but love it. here's the idea, toggle a light on and off while changing the display. Sounds simple but im stumped. Here's what i got, can someone assist in making improvements? I've been at this for hours.
don't mind the mess.. a lot of stuff has been taken out to zero in on the issue

Does an example sketch from the touchscreen library work with only the touchscreen connected?

I dont have any hardware set up yet but have it written to print the outcome so i can test before assembly

Okay. Show what you observe, and describe how you want the results to be.

This is what my screen looks like and the other blanks dont matter right now, the goal is to touch the button labled "light on" (a relay) and turn on the light and the same function for each other options i have. So i need to make a switch that allows me to select a function and turn that function on, then the reverse and to output the lable on the button corresponding.

The issue is it lets me select once, and it turns on, but not off.

I only have singled out the "light on!" Button to figure out how to complete the action vs having to worry about positions of every button.

Im new to this man, but im tenacious lol help if you can

I figured out on my own! Thank you
