LED Lesson Summary

In this lab we will learn how to make an LED blink.

In this lesson you will learn the following programming commands

Programming Code Function
int creates a variable to hold the value of a number
pinMode() configures an output inside the setup() function
digitalWrite() sets power to a specific Arduino pin from 0 to 25
delay(     ) makes the program pause before moving on to the next line

 

LED stands for Light Emitting Diode. It is basically a cheap, simple light source.

Light Emitting = light comes out of it

Diode = current only flows in one direction.  This is why they don't work if you put them in "backwards".
