Read battery voltage from batteriebattery which is powering arduino
Read battery voltage from batterie whowhich is powering arduino
I have a 5V arduino pro micro. I want to power it with a 3.7V lipo.
- Should I use a step up module to convert it to 5V?
I also want to measure the voltage of the battery.
- How can I do this? Because I read that the power source also the reference voltage is so I cant measure it with an analog pin right?
Because I read that the power source also the reference voltage is so I cant measure it with an analog pin right?
I also use a lipo charging module to charge the battery.
Thanks for helping!
