 We now write our first program to make it blink. Here's the program code:

 Note: when handling textual information in the Arduino programming language you need to use double quote marks. In this programming language "digitalWrite" represents text (d followed by an i, followed by a g, and so on, spelling the word digitalWrite), whereas digitalWrite (without the double quotes) is a reference to a feature of the programming language which allows you to control the voltage on various pins.

 So that's the end of the 1st lesson.
-Once the rest of the group has got to this point there will be another short presentation on programming concepts before moving onto [[stage_2|Tutorial 2]]
