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 ...

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.

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 ...

The wiper of the 10K potentiometer is wired to A0 of Arduino (5V-A0-GND), while anode (A) of the test LED is linked to D5 through a 220Ω-470Ω resistor and cathode (K) to GND. #include ...

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 ...
