Hi!

Just for a proof of concept, you can make do with just some wire and buttons - but a soldering iron and solder would make it much nicer and more reliable. I'd strongly suggest https://pine64.com/product/pinecil-smart-mini-portable-soldering-iron/ if you wanted to go that route.

But without an iron, just strip the plastic shielding off the wire (you can use your teeth in a pinch) then twist the wire braid with your finger so it's nice and smooth, poke it through the holes in the Puck and twist it back on the other side - see the attached.

You just need two wires per button - to make it easy put one on 3V and the other on a signal wire (which starts with D, like D1), and the tutorial at http://www.espruino.com/Pico+Buttons (while for breadboard and a different device) does give you the code you need.

Hi Gordon,

That's great, thank you for the information. I have just purchased a Puck. I will go with the non-solder option for the proof of concept.

So if I were to attach a single button to the Puck, I could attach one wire to D1, and one wire to 3V. If I wanted to attach a second button, which holes could I use? It appears that there is only one 3V on the Puck.

I've had a look into buying some wire. I can see that I need stranded wire, like these. Which AWG wire size is most suitable for the small holes on the Puck?

Thanks
RS
