Hello guys, I wanted to ask it is possible to measure overall current consumption of my Arduino with all my devices and components connect to it? Like all motors and sensors are connected and measuring their current consumption when they are working, I connected my Arduino Uno using USB and I just wanted to see how much current is consume by them. Can I achieve this ? @@
Yes just put a current meter in seriese with the power lead. Or if you are not up to that you can buy one of these. https://cam-do.com/products/usb-power-meter
Lots of other models on the market as well.
Is it possible to measure overall current consumption when stepper motor are connected to it? Connected to it with series.
Of course. As per #1. Just make sure your amp meter can handle the expected total current.
Also if you are measuring a changing load then your meter is likely to only read the average current, not the peak current.
