In open lab today at first I got with Ivan and Jon and we started to work on the M&M sorter. We put a color sensor up to it to record the color coding/numbers of the M&Ms inside the sorter. After that we got a drill for an intruder. We sat inside and waiter, after that we went back to working on the M&M sorter and realized we dont know how a relay works because I was absent. So I went on the computer and researched it.
