Hi everyone. First-time poster here. I’m an amateur robotocist but got my hands on a grant and am feeling that I’m in a bit over my head! Basically, I’m tearing my hair out trying to find a simple, 12 key USB number pad with digits 0-9 and either an asterisk or enter button. Extra bonus if it’s illuminated. Catch is — it has to be durable, able to withstand extreme desert conditions.
I’ve found some durable ones but they’re not direct to USB. I’ve read a bit about encoders, but as I said above… am a bit of a novice, and I’d just want it to go straight into a Raspberry Pi. Any suggestions? Thanks in advance.
