turning on Pi with GPIO pins

Wed Apr 18, 2018 1:03 am

i was reading about how to connect a momentary switch to the pi by connecting the switch to pins 5 and 6. pin 6 is ground and i think 1.5 volts on pin 5.

what i am finding is if i just touch pin 5 with a metal probe the pi will turn on, without touching ground.

is that supposed to happen? i thought you had to short those two pins for it to turn on.

i was also trying to measure the voltage drop when the switch was pressed. when i touch the probes of my multimeter to the pins the pi turns on. i guess the act of using the multimeter completes the circuit?

you can tell im a little new to this.
