The blink interval is fixed and has to be changed by changing the Arduino code. The second part of the video shows how the potentiometer is replaced by a rotary encoder. The button on the encoder ...

Blink One of the initial Arduino tutorials is Blink, a program that simply turns an LED on and off for one second each. It is a nice demo that doesn't require any external devices and can be written ...

Chapter 1, page 11 This code is basic but allows the reader to gain insight into key elements for several other projects in this book. It combines two pieces of code that are listed in the examples ...

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 ...

Once the code is uploaded to the BlinkM, you essentially have a micro Arduino running at 8MHz with a built in LED and 2 I/O lines (5 if you snip off the LED).

Official Arduino Example Tutorials: The Arduino computer software is loaded with tons of examples for you to use in your own code or to run through as a learning experience.
