2.2.1 Multiple Blinks of an LED
Lesson Description
|
In a previous lesson, we saw how to blink an LED once by turning it on, pausing, and then turning it off. The example in this lesson shows how to extend that code to do multiple blinks. Remember that the LED module is connected to pins 11, 12, 13, and GND on the Arduino as shown in the diagram on the left below, so that the pin labeled "R" on the RGB LED module (the red LED) is plugged into pin 13 on the Arduino, the "G" pin (green LED) is in pin 12, the "B" pin (blue LED) is in pin 11, and the "-" pin is in the GND, or ground, pin.

Example 1: Multiple Blinks of an LED
Use the Arduino to turn on the red LED in the Barobo RGB LED module, wait two seconds, then turn it off. Wait one second, then do the same for the green LED. |
