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 ...

The circuit is an Arduino RGB LED controller running on a sweet ‘n’ simple code,but with a little hardware surprise outside the Arduino board. You can add a bit of luxury to your aquarium or flower ...

You can build an LED circuit fairly easily, but then all you have is an LED circuit. Learning to build a robot arm will teach you how to breadboard a circuit, how to program your Arduino, and how ...

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 ...

A simple circuit, but it just goes to ... 300X Arduino. British Commuters ... on it. Parts list was dirt simple: 4x LEDs, 2x caps, 2x transistors, 4x resistors. No 555, no CPUs, just a 9V battery.

While it’s great to look at professional maker projects that use motion tracking cameras or giant 3D prints that break the bank, it’s also nice to look at simple Arduino builds too. This ...

[Henryk] just sent us his latest episode of simple LED circuit puzzles. In front of the camera he solders one pin of each of the 3 LEDs to a different switch. He then puts the three assemblies in h… ...

This boost circuit implements current mode control and senses the LED current via resistor R14. The output voltage is boosted to just over 30V to drive 10 LEDs at a regulated current of 0.35A. Often, ...
