My daughter (10) and I just built the metronome kit, and there is a problem.
When the metronome is turned on, the following happens:
- display flashes brightly;
- "r22" is displayed for 1/2 second;
- "tap" appears on the display
(display seems to "shimmer": brightness changes rapidly and slightly?)
Taps are not being registered; not gentle ones, nor rough ones, nor banging
the whole thing on the table
Display never goes bright.
How do I troubleshoot this? What should I look for? Busted buzzer?
Of course, the kit is completely built, so all the soldering is covered by the
battery holder, which is glued and soldered to the PCB
Any help is appreciated.
