Hi guys, how can I measure the overall current consumption of my stepper motor + sensors + arduino uno? Since multiple components connected to 5V, so I wired out the 5V to the breadboard. If I wanted to measure it, how can I do it?
 

If your query is how to measure current overall avearge value , then use an ammeter in the +5V line.
 

I mean when I connect all the components to my Arduino Uno, I want to measure how much current the system draw. So, just by connecting to 5V line there can measure it?
 

Put ammeter or multimeter in ammeter mode in series with your power supply and loads that is red probe to +5V and black probe to all other +5V connections to your circuit (loads).
