Voltmeter for a 8.5V battery and INA219
Hello! I need to build a voltmeter up to 9V to test a battery. I’m going to use “Zio Current and Voltage Sensor - INA219 (Qwiic)” https://www.sparkfun.com/products/15176
I’m familiar with BS1 and BS2 only. I think is time to start learning the BS2pe. I need a piece of code to get me started on this project. I only need to read the voltage of the battery for now. Any help!
Oh Thanks JonnyMac for your advice.
