Arduino sketch

In the getting started guide (Windows, Mac OS X, Linux), you uploaded a sketch that blinks an LED. In this tutorial, you'll learn how each part of that sketch works. A collection of contributed code snippets and sketches.

If you want to lit an external LED with this sketch, you need to build this circuit, where you connect one end of the resistor to the digital pin . These simple programs demonstrate all basic Arduino commands. They span from a Sketch Bare Minimum to Digital and Analog IO, to the use of Sensors and . DIY Etch A Sketch Use two dimmers to draw on your computer screen, just like an Etch-a-Sketch.

Start up the Arduino software and open the Blink example sketch, as you did in Lesson 1. The sketch itself is in the text input area of the Arduino . The next step is to write the 'setup' function. As we have learnt in earlier lessons, the setup function runs just once after the Arduino has reset. Copy and paste these sketch examples into your Arduino IDE and begin to experiment with MakerPlot.

Some important things to keep in mind when writing your own code: An Arduino program is called a sketch. All code in an Arduino sketch is processed from top .
