Step 3How to build it: Wireing the buzzer
The buzzer should have two leads coming off of it. One red and one black.
Solder the red lead to the positive pad of the cell.
Solder the black lead to the negative pad of the cell.
Before continuing to mount the buzzer take the time to test the connection. Put the cell next to a bright non-cfl light or the sun. If it buzzes then you got the soldering correct. If not switch the leads and try again.
Once properly wired, secure the buzzer to the back of the cell with some hot glue.
