Hi everyone!
I just finished my MK139 and I’ve a question.
I don’t know how I must test it cause I don’t understand the mini picture about the installation.
Can somebody explaine me how I must instal it?

Thx! :slight_smile:

Please be more specific on the nature of your problem.

I don’t know how I must instal it.
I tried to connect it with an adapter but it don’t do anything.
Only the first LED flashed on when I clapped.
Can you tell me how I must instal and connect it.
