My circuit consists of 3 mosfets which acts as electronic switches and is connected to 3 leds the each of the leds are further connected to ina219s respectively.the switches are turned on serially if i turn on mosfet 1(switch 1) all the ina219 gives out same values. please help me out..... the code used is given below. thanks in advance...
