Hello someone.
I have a small device I have put together from a small watch. It now says "beep" when the battery is connected. I want to couple it to an Atmega16 (MCU) so I can hear the beep when it restarts (by watchdog timer). The problem is: When I connect 1.5V battery it works fine, but if I make a voltage division from VCC 5V to get 1.5V to feed the thing it doesn't "beep". Why is that (not) happening?
Hope someone can help me!
