To build this project, all you need is three main components: an Arduino Uno, a 16x2 LCD, and a push button. You can connect everything to a breadboard to keep it simple.

Building radio receivers from scratch is still a popular project since it can be done largely with off-the-shelf discrete components and a wire long enough for the bands that the radio will receive… ...

It's also where you can find information on some of the principles and technologies behind the Arduino boards, such as the I2C ... find Arduino projects to try ... LED, DC motor, LCD ...

Seven-segment displays and monochrome LCDs are fine for most projects, but some things simply look better in color. [John] over at the Little Bird Electronics blog recently wrote up a tutorial demo… ...

Sometimes, the best Arduino projects are the most ridiculous. Case in point, this motion-detecting squirt gun.The idea is simple: when it detects motion, the spray gun activates.

An Arduino can be used to test the life of any battery with less than 5 volts, Boxall says. So, for a quick way to see how much juice your AAA, AA, C, or D batteries have left, build this Arduino ...
