LED Sequence
LED Sequence
I started by following online schematics to build an LED matrix, Sodered the matrix following this example.
After completing the matrix I proceeded to go on the web to find programming forums for this matrix. I found this forum and used it as an example for my code. Adding the code I learned from a class I had completed what I had set out to accomplish.
I would like to use code like this for some sort of signage coding.
/*1.) On your breadboard, create a circuit with at least six (6) LEDs - each on their own Arduino pin.
2.) Write and upload an Arduino sketch that times the LEDs to blink in some kind of sequence
3.) Document your circuit, code, and a VIDEO of your working sequence - and include these in your blog post.
***Any video should be included as an embedded youtube video!
*
4.) Include a brief (1-2 sentence) reflection on this process. Consider challenges and successes encountered.
5.) Include a brief (1-2 sentence) thought on a potential light-based art work. (there are no wrong answers here!)
Bonus Points:
1.) Use PWM pins to create a "fade" effect for one or more of the LEDs.
2.) Avoid using the delay() function - and time your sequence only with counter variables!
3.) Use a for() loop to manipulate multiple LEDs at once!
