Here are the details for my second attempt at a wearable Arduino. (See first attempt here.) I’m struggling a bit to create something I actually want to wear, but this is definitely better than my last attempt.
I used the Lilypad ProtoSnap Development Board along with the Coin Cell Battery Holder mounted on sparkly felt. The skeleton pendant came from a craft store and was attached with “invisible thread” (made threading the needle a challenge!).
The coin-cell battery is a definite improvement and I like the way the LEDs are designed to be sewn in. Because I’m trying to avoid soldering and it’s so easy to cross wires while sewing circuits, I decided to use traditional wires for the sensor.
Speaking of sensors, I ordered my pulse sensor on eBay. It was less than a fifth of the price of the official pulse sensor, but it took weeks to ship from China, came with much shorter wires attached, and didn’t have the earlobe attachments.
As far as the code was concerned, I was able to adapt the code from the Pulse Sensor website with only a couple of changes, so it was actually the easiest part of the project. Download code for project here. Adapted very slightly from code found here to work with Lilypad. It was pretty straight forward to choose the ports.
