- Controlling voltmeter from arduino?
- 26 Dec 2016 02:37:54 pm Permalink
I would like to use a voltmeter as an analog display for an arduino, eg i want to control the position of the needle with the arduino. I am assuming it's more complex than just putting the + of the voltmeter to the arduino PWM pin and the - to GND, but cant find anything on the internet. All the results i find are about measuring voltage with an arduino, not controlling a voltmeter from an arduino
