Brushduino – Arduino Meets Toothbrush
You knew it was bound to happen. We have seen Arduino’s used in everything from toasters to coffee machines and now we see the Brushduino. The cool hacks knows when you are brushing via an accelerometer that you attach to your toothbrush. By knowing what your doing the unit will tell you when it’s time to move to the next section of your mouth.
“It’s basically all LED’s. There are 6 white LED’s that correspond to the six regions of the mouth that I want to highlight, there are four green LED’s for showing progress and there’s a speaker I pulled out of some broken toy that’s there to entertain the children while they brush. The multi-strand wire connected to the three analog inputs on the Arduino also supplies 3.3v and ground to the accelerometer. The cable itself is an old ADB keyboard cable from my old Mac SE/30 from back in the day. It’s been laying in my junk box for ages. There are also some current limiting resistors for the LED’s and a bunch more of that lovely AWG30 solid core wire I like so much.”
