How-To: Binary clock using a Freeduino SB 2.1


Solarbotics recently released its own version of the Arduino microcontroller development board. They based their board on the Freeduino design. We thought this would be a good opportunity to review the new board as well as present a How-To about building a simple binary clock. Along the way we’ll cover some basics on attaching LEDs and switches to a microcontroller.
