Christmas decoration circuit board help

[Paul Sinkinson]

Hello - first time poster and general newbie. I'm hoping someone might be able to offer some help...

I have a Santa Christmas decoration that moves, lights up and plays music when activated by sound. I have disabled the sound by snipping one of the wires to the speaker, however disabling the sound activation is proving a little more difficult. All I would like it to do is move continuously without any sound and without the need to be sound triggered to start again.

I have accessed the circuit board and the detached the wires to the piezo speaker - the decoration only moves when I touch the wires together but then will stop once the song has finished, touching them again starts the motion but again, will stop after a song. Touching them together briefly during the motion will stop the motion and then touching again restarts the motion etc. I assumed it's like an on/off signal chain.

Any suggestions? Many thanks! Photo of labelled circuit board attached

Desolder the black motor wire from M2- pad top left of the pcb and solder it to the pad marked V-K2 - 3rd set where the battery and piezo wires connect.

brilliant! That worked! Thank you

Hi there! To bypass the sound trigger and keep your Santa decoration moving continuously, you might need to simulate a constant trigger signal. One approach is to connect a resistor (around 1kΩ) between the wires you snipped from the piezo speaker. This could provide a stable "trigger" signal to the circuit.

Apparently not. The OP said he has it working.
