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 ...

Inside each box goes a colored LED, wired back to the Arduino. For the software, [Will] is using a floating analog pin as a source of random noise, and from there comes up with how often each LED ...

I would like to note that since the 68000 has 68,000 transistors, it’s still possible I’m using fewer transistors to blink a LED than I would with an Arduino.

In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more. Every step will have the code, the schematic, photos of the project ...

Like almost all Arduinos, has a built-in led – the green one on the left in the photo. And it has a pair of yellow leds – called TX and RX – to indicate traffic on the serial bus. Except, on the Micro ...
