Lync presence (busy) light with 5mm LEDs

When I am at work, I use headphones; a lot. About half the time I am listening to music, the other half I am talking with someone on Lync (Skype for Business). This has made it difficult for my colleagues to know whether I am available or not, so I get interrupted when I’m on the phone. I needed a way to communicate my availability, and Lync already does a pretty good job with this; it’s red when I am in a meeting, on the phone or simple do not want to be disturbed. Yellow when I’m away; I don’t think the away part is a problem, when my chair is empty I am usually away… And green: come on in! Enter the Lync presence light, or busy light if you will. Yeah there are some you can buy, but where is the fun in that? So I made one using an Arduino board.

Lync presence (busy) light with navigation LEDs

This is my second generation Lync light, I built the first one back in May 2016. It worked fine, but it only had three 5 mm LEDs. People who knew about the module noticed, but a lot of people didn’t, so it did not have the effect I was looking for. That’s why I decided upgrade it, and this time use bigger and brighter lights! I found a pair of maritime navigation lights on eBay that were small enough to fit on the top of the enclosure. They are much harder to miss, than the LEDs :) I still use the same Arduino firmware and bridge software as before, just upgraded the hardware.
