Available in red, green or blue, these little LED voltmeters are the quick and easy way to add voltage readout at various points in your project.
This meter has a third wire for the measured voltage allowing for a greater range of measurement.
Just connect the red to wire positive and black wire to negative to power the meter and then connect the yellow wire to the power source you want to measure, that’s it!
Want some mounts for these?
Here is another one. (Though please use a nicer looking filament!)
And finally this one is the one we use to bolt up on to our printers.
