AAA to CR2032

Post by lucidnightmare » Sun Nov 05, 2017 11:30 am

Hello all! :) I am trying to figure out how to power one of these by a few CR2032 button cell batteries instead of 3 AAA batteries.

The circuit probably requires 4.5V and CR2032 cells deliver 3.0V. Much easier just to use the cheap AAA cells.
