The DIY Team spent this past weekend at the Berkeley Art Museum hacking sounds using MaKey MaKeys and Quartz Composer. Kids used construction paper and tin foil to create their own one of a kind musical pad/keyboard and one kid even managed to create a track using his face. Make your own weird sounds and become a Hardware Hacker.

Arduino Project: Simple Soil Moisture Sensor

Earn the Sensor Hacker Skill by building a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. Two wires placed in the soil pot form a variable resistor, whose resistance varies depending on soil moisture. This variable resistor is connected in a voltage divider configuration, and Arduino collects a voltage proportional to resistance between the 2 wires.
