I wanted to build something for Valentines Day earlier this year. I came across the heart STL on thingiverse, and had received a bluetooth circuit playground towards the end of 2019. I put them together and created a little bluetooth scanner that shows a given color based on the number of devices found (red, blue and purple but easily changed in source).
Main bluetooth loop and led helper functions.
