This is a very simple arduino project where a led is turned on by setting the pin 13 as output, then write it with a high value, in our case that means that pin 13 will deliver 5 volts. Advertisement ...

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. Anyone interested in creating interactive objects can “play” with Arduino! Described ...

This project demonstrates a simple LED flip-flop pattern using an Arduino Uno. The LEDs will toggle between different colors in a sequential pattern, creating a flip-flop effect. The circuit consists ...

An Arduino is a popular open-source single-board microcontroller. Learn how to program one and let the possibilities take shape. By The Big Book Of Hacks Published Jan 10, 2013 3:00 AM EST Get the ...

The hardware is built around an Arduino One, a character LCD and a sensor made from a blue/white LED and a simple photo transitor (I do not have a datasheet but it seems to work well). Because of the ...

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 ...

[Patrick] was prepping for some future projects he had in mind, for which he will need a simple 2D array of addressable LEDs. While it is certainly possible for him to build his own LED array and c… ...

[PatH] from WhiskeyTangoHotel choose the latter route, and built a super simple LED controller for his KLR650 bike. He chose a commonly available 18 W light bar module containing six 3 W LEDs.
