i mean like gpio 2 it is a 5V voltage supplier pin. and gpio 6 is a ground pin. but in gpio 6 its also show same voltage as shown in VCC pin i mean in gpio 2. actually in all 40 gpio pin its show a 5v voltage .. i use tester to measure the voltage....gordon77 wrote:Measured relative to where?
i use this electric tester to check the voltage and the bulb will be switch on same as on on pin2gordon77 wrote:Where are you connecting the other lead from the meter when measuring pin 6?
