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 ...

It is a pretty common first project to use an Arduino (or similar) to blink an LED. Which, of course, brings taunts of: you could have used a 555! You can, of course, also use any sort of oscillato… ...

'Loop' is the main meat of the program. Anything placed in here will continuously run for as long as the Arduino has power - so for the Blink example, it repeatedly turns the LED on and off.

Since we’re just getting started, try this simple modification: changing the LED’s blink rate. Just alter the numbers in the delay commands, then upload it to your Arduino board with the arrow ...

If you've not got that project to hand, don't worry. We're going to be using Pin 13 of the Arduino to control the LED, so you want to go from there to the positive (longer) leg of the LED, from ...

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 Arduino is a cheap, fun way to get into building your own electronics. It can also be daunting to get started. Here, we’ll show you how to get a start-to-finish Arduino primer with a killer ...
