  • I have this sound detector powered by two 3V COIN CELL BATTERIES (with a diode to drop voltage down to 5.3V), and it doesn’t function properly. The red LED turns on and stays on until power is switched off. Why does this happen? Is it a current issue? (when I switch to 3 AA batteries the sound detector works fine). Please let me know if you have any insight about this so I can modify accordingly. I really would like to use two 3V coin cell batteries.

No public wish lists :(
