Week 12: NETWORKING & COMMUNICATIONS
MIC to LED ARRAY (toward final project)
Networking and Communications is conveniently the last piece of the puzzle for my final project.
I basicallly need to figure out how to make my LED array respond to the information gathered by the mic.
This week I finally made my mic input pick up sound info, after much consternation:
All week I was getting NOTHING, just steady static, NO response to sound:
Finally, after a bunch of soldering and de-soldering:
The problem I think was a small strand of hair or something like that that was connecting the + and - of the mic.
I am not sure, but that was probably it... It was really driving me to despair.
(Thanks for your help Yadid!)
Now I finally have a working mic PCB and a working LED array PCB.
I am greatly indebted to guru Matt Miller for explaining some basic concepts in programming to me. It was so helpful.
I basically needed to program the following:
Do a loop, 1-2-3-4
Send High and Low bytes via output pin (MOSI on 6-pin header)
For the MIC board:
So here's the code:
For the LED Array board:
Get char from input pin (use MOSI on 6-pin header)
Read High and Low bytes and MAKE INTO 16-bit int (VAL)
Write what to do with that... how to blink
Here's the code for that:
So I programmed each of them separately, and connected up with a battery source for the LED, the mic conncted via serial for power,
and the two grounds and MOSI's connected... AND NOTHING.
CRUNCH TIME!!!! (final project update)
WHAT I NEED TO FIGURE OUT:
PROGRAMMING: GLOW-- Looked at RGB c file, still can't get it to work...
Program LED array to respond to sound info from mic PCB
UPDATED SCHEDULE FOR FINAL WEEK:
Get programming figured out
Fabricate Leaf components on lasercutter
Attach vinyl-cut receiver pads and link with bronze wire
Stuff all leaves and PCB's
Assemble components to one group of LED leaves
Install in situ
My white LED's are 20 amps, not 10 amps, like the green and red 1206's in inventory. Do I need to change the resistance on PCB?
How do I physically connect the LED PCB with the mic PCB? With the 6-pin header? Cut power line?
How do I make my LED's glow?
Can a 9-V battery power both boards?
