Hi every body
I want design a circuit to measure load current(LOW COST and reliable)
I chose the blow circuit but it doesn't work
(changing the load current doesn't cause voltage variation in a range)
How can I correct this circuit.
load current variation is 3mA to 300 mA and I want to convert it to 0V to 5 ( and the use the ADC of micro-controller)
