But, since you can’t actually generate a changing voltage directly from digital microcontrollers like the Arduino, it’s necessary to use “fake” an analog voltage. As Tom Igoe notes in his page on analog [...]
Physical Computing Assignment – Analog Input
My first assignment in Physical Computing was to create something along the lines of a “love-o-meter,” aka, one of those games that “measures” your sexiness (from ‘Cold Fish’ to ‘Hot Stuff!’, or something similar) using analog input from variable resistors. Riffing on this idea, I came up with the concept of a “massage feedback shirt.” [...]
