Yes you're right now I remember!
Although this was my original plan, when starting tinkering, sharing and getting feedback, I got other ideas.
One guy in the telegram group of the event was concerned about the idea that the device could explode because of extreme levels of happiness. This is because the event is so immersive that is common to get over excited.
So I thought that it would be cooler to design a happiness overdose detector, but how could that be done??
I started to change the circuit and getting comfortable with the idea that instead of trying to configure things to get the thing that I wanted done, I could try to get advantage of the default configuration and figure out how I could maximize the value of the information that is already there without processing.
I got to a minimum set of Bits >> usb power + dimmer + bargraph + CloudBit
and started analizing the data I was getting. I found that moving slowly the dimmer, when you reach the trigger level, the value registered was near 80. But when moving fast, the value registered was more likely 90.
So I concluded that maybe with that minumum set I could get some results. I see 2 cases:
- Someone is happy but is deciding between turning 4 or 5 lights
- Someone is extremely happy so there is no doubt that the way to go is to turn the dimmer all the way up with confidence
So getting a 90 would mean a happiness overdose dectection
