PING)))

Filed under: Electronics and Experimental Systems — Mia @ 3:09 pm

Parallax makes an ultrasonic distance sensor that interfaces with Arduino’s micro-controllers. This is a set-up of PING))), Arduino UNO 3, Arduino’s motor shield, a voltage regulator, and two 12-volt brushless fans. The fans rev up when PING))) detects anyone less than a foot from the sensor. Learning to use millis instead of delays in the programming code allows more frequent updates to the RGB LCD (red-green-blue liquid crystal display). I mounted the LCD on a backpack that has user interface buttons for color control. The next step is to create blinking eyelids that blink faster as someone approaches.
