Tell us about yourself!
Also, one last thing: the amps written on the adapter is the max amps it can support, so it won't necessarly be that much current in the DC-DC converter?
But then does that mean that the input has to be greater than 5V? Because I want to be able to mesure 1V for example, and my voltmeter needs 2,7-5V to light up
Does it work with regular diodes? I can't find any Zener diodes.Also, can someone explain to me what a Zener diode is exactly? I don't understand very well.
Is it possible to replace the 2 wire digital voltmeter with a 3 wire one without adding an extra power source? My voltmeter needs a 5V current to light up
