Ohms Meter Multiples resisters

Hi Guys,

Anyone could help me? I have a ckt that I made with 5 resistors (90Ω, 90Ω, 90Ω, 120Ω, 120Ω).
I would like to create a tester using a arduino that measures all the 5 resistors at the same time and if they all have the equivalent resistance then a GREEN light would turn on as PASS otherwise a RED light as FAIL.

Any help will be appreciated,

PS: I am newbie :wink:

You need to show us the circuit..

by "the equivalent resistance" you mean what exactly?

Are these resistors connected to each other when you test them? If so how?
