Topic: Lasers not working, voltage issues?
Hello,
I've started with assembling my own scanner but I'm running into problems.
I've tried everything on Raspberry Pi Model B+ V1.2 and Raspberry PI 2 Model B V1.1 and can't get lasers to work.
I've only connected lasers and they don't work, and I'm also getting weird voltages, ULN2003A giving 2.7V on pin8/gnd and 2.7V on out1 and 2.4V on out2?
Can I find somewhere what should I be getting?
The camera is working.
Also I've followed this wiring diagram, is something not right here?
