I want to use my PiZero which I’m currently setting up as an ammo counter (and led light controller) for a Nerf Blaster I’m building. This side of things is fine, I have a lovely little OLED screen for the ammo counter.
Usually I wire in a simple LCD voltmeter into the circuit to keep my eye on the voltage on the LiPo so it doesn’t drop too low.
I was wondering if I could get the Pi in on the voltmeter action and get the voltage to display on the screen along with the Ammo count.
From information I’ve gathered it appears I need an ADC and there appears to be the Automation pHat that I believe fits the bill. So my question is, will the automation pHat allow me to measure the voltage from the 3S LiPo most likely with these specs?
Voltage: 3S1P / 3 Cell / 11.1V
Discharge: 65C Constant / 130C Burst
And will this still let me use the OLED screen etc?
