LilyGO T-Display-S3 and photoelectric sensor
Posted: Sat Nov 09, 2024 4:31 am
Hi, new to the forum.
I have a LilyGO T-Display-S3 and have the touch screen and the UI all functioniung correctly.
I am strugling with the pins and connecting the photoelectric sensor and getting it to work.
Which pins to use seems a little confusing, or it may be my noob coding skills.
If any one has some advise or help on getting this to work it would be much appreciative.
