When a father makes a gadget for his unborn son, that’s true dedication. Corey Menscher designed and built the Kickbee for his pregnant wife. The baby kicks her stomach, a piezo sensor reads it and another module twitters the response for all to see. Can you guess what microcontroller is used to control all of this? Take a guess.
Yup. The Arduino. Specifically, an Arduino Mini with a Bluesmirf Bluetooth module. I’m no Twitter fan but this is badass.
