I got introduced into the world of Arduino when two friends informed me about this little device independently from each other. I read about it and was sold immediately. What if I had this so many years ago, how much would I have invented already, what would I have made? What would my house have looked like?
I ordered one directly and there I was playing with lights, sensors, etc. But then? ..... it has the potential to control everything, but what? What should I make?
I think this is where more people get stuck. What should I do with it?
Coincidently I just finished constructing
a coffee roaster, made from an ordinary popcorn machine. In basic it works by a fan blowing air past a heating element through the green coffee beans. By controlling the fan speed, I was able to control the temperature of the air roasting the beans. But, the roasting process turned out to be quite hands on, as the temperature needed to be kept constant following a profile, which was done by measuring the temperature the whole time and adjusting the fan speed with a pot meter.
That, I thought, should be automated....
