Puck.js, Raspberry pi camera

Hello, I was hoping to use a Puck.js to trigger a camera connected to Raspberry pi zero with WiFi/Bluetooth.
I've been looking at the tutorials and not knowing were to start. I'm guessing this should be possible, I'm just not sure were to start.
Thanks

Hi @user111161, is the inquiry more on how to use/code Javascript, or how to interface with another device?

Thank you, I'll review the suggested link. I'm looking at how to interface the Puck.js with a Raspberry pi Zero using Bluetooth

I think you've basically got two options:

• Use Puck.js as a device like a keyboard, and use it to send a keypress that your code then acts on: http://www.espruino.com/BLE+Keyboard
  
• Have an app on the Pi that scans Bluetooth and then acts on the data received. There are a few ways to do that, but maybe the easiest is this one: https://www.espruino.com/BLE+Advertising
  
  

Hope that's some help!

Thank you, this helps
working through the following example
https://www.espruino.com/BLE+Music+Control

setWatch(function(e){
 print(e.time - e.lasTime);
}, BTN, { edge:"falling",repeat:true,debounce:50});

the puck returns "NaN" on press button, the puck is on 2v04

I figured out my mistake now works
Thanks
