Hi,
Are you measuring a short circuit here with power ON. and the DMM in RESISTANCE mode?
You cannot measure resistance with a DMM in a circuit that is powered up.
What VOLTAGE do you measure across those two points.
Can you please tell us your electronics, programming, arduino, hardware experience?
Can you please post a copy of your circuit, a picture of a hand drawn circuit in jpg, png?
Hand drawn and photographed is perfectly acceptable.
Please include ALL hardware, power supplies, component names and pin labels.
Thanks.. Tom...
