I put together the WSAK204 Electronic Cicada according to the instructions but it isn’t working.
When I connect the battery and switch it to “on”, the LED and buzzer work for 1/2 a second and then stop.
Any idea what could be causing the problem or how to troubleshoot?
I double-checked the soldered joints. Every joint was soldered from the “solder side” except for the battery and piezo speaker wires. I positioned the setting of each the trimmer according to the instructions.
I looked at the circuit diagram from WSAK204 Electronic Cicada - circuit diagram but I still don’t know where the problem could be.
I guess my next step is to take a multimeter and test continuity between the components.
