below is the analog input lab from last week’s class.
i’ve been thinking a lot about how sensors could be helpful in collective living situations. i want to make a thing that would let you know when you’re running low on things like soap, rice, etc. it would attach to the bottom of the dispenser/jar/whatever, and when the analog input was between certain numbers, a yellow light would light up and then a red light would light up. it’s basically a scale with a light system connected to it.
the problem is that you’d have to keep the program running all the time, which is a goofy use of electricity. but maybe it could turn on when the room lights turn on (or some other cue), check analog input, light up if it needs to, and shut off if it doesn’t need to.
