Hi, @swordspider
Welcome to the forum.

https://forum.arduino.cc/t/how-to-get-the-best-out-of-this-forum

Can you please post your code?
Can you please post a copy of your circuit, a picture of a hand drawn circuit in jpg, png?
Hand drawn and photographed is perfectly acceptable.
Please include ALL hardware, power supplies, component names and pin labels.

Can you please post some picture of your project?
So we can see your component layout.

Thanks.. Tom.. :grinning: :+1: :coffee: :australia:
