Work with Arduino
A small device I built and coded.
Using Arduino I built an automated bubble blowing device. The bubble wand is on a servo motor that is rotating in a 180 degree radius pausing at the furthest degrees of rotation. The wand rotates in front of a fan and bubbles are blown out. There is an ultrasonic sensor on the top of the box that halts the entire system if it detects a hang in front of it.
