A quick PWM test from an Arduino to control the needle on a 3/15V analogue volt meter.

Purchased the panel meter for about £2.50 and just need to place either a 3K or a 15K resistor in series to select either 3V or 15V measurements.

I connected to an Arduino using a 10K pot instead set to around 5K so I could supply 5V and use PWM to position the needle where I wanted.
