Arduino 2-Digit 7-Segment Display Counter | Part 1

This month’s Arduino project is to build two 2-digit 7-segment LED display circuits and sketches, one that counts up and one that counts up using mini push buttons. The next posts will explain the circuits and the Arduino sketches. (Here’s a simpler, 1-digit 7-segment display using Arduino). Materials: Arduino Duemilanove (or Uno) 1 2-digit 7-segment display [...]

An Arduino for Any Project

The Arduino is based on the microcontrollers from Atmel. Here are current Arduinos available (the architecture is open source, and anyone can build their own “Arduino” based on the technical specs that are available for download from the official Arduino website). Duemilanove: “Duemilanove” means 2009 in Italian and is named after the year of its [...]
