Cobbled together some "snap to pin" wires and tinkered with the arduino and his snap circuits with him for a while. When he got bored, I started learning about analog inputs on the arduino uno. I've got a pile of sample data from a photoresistor that I might try to graph with GNU Plot or maybe guile. It'd also be neat to read the serial port live and do something with it. Time for a celebratory burrito and cup of !coffee in the mean time. https://loadaverage.org/attachment/3065793
