Hi,
This is a current measurement circuit, I am not sure the 7805 's circuit is right.
Help please.
Thanks
Adam

The 7805 supplies a regulated 5V to the Vin on the arduino, then the 5V output from the arduino feeds the sensor, but that 5V will be less than 5V because of the drop across the arduino regulator.
