The remote control is used to turn the Pi on. The Arduino reads the IR code from a remote and simply powers up the Pi.

The idea was that the LED itself could be used as a rudimentary temperature sensor, and the Arduino code would turn the LED on and off when a change was detected in its forward voltage drop.

The Arduino is an open-source electronics prototyping platform composed of two major parts: the Arduino board (hardware) and the Arduino IDE (software). The Arduino IDE is used to write the program ...

This is tutorial number 1 from our series of Arduino tutorials and in this part I will talk about blinking an LED using the one already available on the Arduino Uno board or using an external LED to ...

If you've messed with Arduino, the inexpensive micro controller, you'll know that you can run a small motor or turn an LED on and off, but anything else - powering a pump, turning on a light bulb ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led - the green one on the left in the photo.
