    Switching positive volt

    Hi, I am only using one voltage at a time. like plugging in a 12v bulb or a 24v bulb. but use picaxe command to switch between 12/24v only 1 circuit for 12 and 1 for 24 current is less than 500ma ( Car type relay, prox sensor,)

    Brain hurts..anyone bored..

    just for info anyone bored and find faults? Here i have the schematic for my project. 24v battery supplying 12v to 5v, for project and outputs for all numerous 5v inputs, for switches triggering 24v out, detecting and measuring a external 24v input

    adc stability for volt meter

    I designed board but professional check/made/ they check for broken links etc. it seems strange as getting 1.5 v to pin c3... seems i get no change on adc reading. but get a change on 1.5 to 0volt on pin... maybe 20m2 is toast?

    adc stability for volt meter

    well here we are again. board was printed and built. 2 of my volt readings are very stable, great thanks everyone... but now one reading is wandering from 150 to 700+ on Word variable W0. this value is greatly changing even if nothing connected when 24v conected i have stable 1.49v at pin c.3? i...
