Hi, for my problem with contact switches,'m trying to experiment every option. One thing i would like to do is to read 2 contact switches using a single analog pin. so that a 00 would be 100 , a 01 200, a 11 300, and a 10 400, for exemple. All that matters is that each combination gets a completely different valu on the analog output.
Since i don't know much about electronics, an someone help me design this circuit?
Thank you
