LArduino LED 6: Interleaved Color Blinking using NB Code
|
Objective: Learn how to use nonblocking (NB) code to do interleaved blinks of different colors, using an RGB LED module connected to an Arduino board that is connected to a Linkbot. "Non-blocking" commands are different from regular commands in that they start their execution and then immediately move on to start the next command in sequence (while continuing their own execution), whereas regular commands do not move on to the next one until the command has completely finished executing. Overview: The pre-placed code blocks use digitalWriteHighLowNB and digitalWriteHighLow commands to do interleaved red-green blinking without using a loop, by suitably adjusting the length of the "low" ("off") time for the red and green LEDs, respectively. After you try out the existing code, modify it as directed in the Problem Statement.
