Short answer, yes, probably. I only got it working on contrast so far.
The top left pot controls contrast.
I used a 2N2222A transistor with 100R resistor on base (yeah, forgot my pull-up resistor, although I'm going to change that to pull-down).

My Creality Ender 3 S1 Plus is a giant paperweight that can't even be used as a boat anchor, cause I'd be fined for polluting our waterways with electronic devices.
Not as dumb as yesterday, but stupider than tomorrow!
