I have a Nano board, which is fed from an external power source. It is getting 24V supplied to it. It is supposed to be 10V powered via an LM317, but on power up the trimpot controlling the LM317 is sometimes set to full 24V!!. I need to measure the supply voltage, and blink the on-board LED if it i…

[image] wiresplus: I don't seem to have found it anywhere, and I suspect it's not supported. 1. Without giving any power, make the following setup as per Fig-1. [nanoPicLM317] Figure-1: 2. Disconnect A5, Vin, and GND wires from NANO. 3. Connect DVM across 1uF capacitor of power supply…

Is there a way to monitor the +VIN voltage in Nano?

And you apply 10V to the AREF pin?

Or were you just thinking it were related to VIN in some way?
