WAV-Trigger not responding to Arduino NANO

Hello!

Since 2016, I’m using a WAVtrigger (https://www.sparkfun.com/products/13660), with my Arduino UNO using Serial connection. I finished this https://www.youtube.com/shorts/9Rzbj-gC … el=LHMAAKE project with that combination as well.

However, because my audio system at home got a huge upgrade (as in, amplifiers ect), I had to redesign the “behind the scenes” space. This resulted in replacing my arduino UNO for a NANO, which is a lot smaller. I didn’t change anything in the arduino code, only the board itself was replaces (also changed the pre-setting board in the Arduino code editor), but for some reason, there’s no way my wavtrigger and NANO can make a connection. Serial Monitor keeps telling me “No WAVTrigger Response available”. I tried putting back my UNO, and it works!

I was wondering if there’s any difference issues that I need to take care of in order to get it working. Both the UNO and the NANO use Digital pin 9 to transfer the serial data to the WAVtrigger. I tried replacing my WAVTrigger with my friend’s, but still the same result. Manually jumping the trigger wires still play sounds, so the board isnt broken.

I hope any of you can advice me in this matter.

Hmmmm…that’s strange. How are they being powered? Can you share a photo of the siring/setup?

Does the Nano’s pin #9 work otherwise? (Test with a different code/product)…the nano might have a problem

Hi,

Thanks for your reply>

I already swapped the nano with a different one. Same result. The wiring is literally;

D9 → RX (Wavtrigger)

GND → GND (Wavtrigger)

I don’t see what I am doing wrong.

Try using a pro mini instead. Small like a nano, but 100% uno compatible.
