   2 decided to start with ultra-sonic distance sensor. need it to read
   3 distance, at distance<=x, pull pin low (trigger as button press)
   4         --this can then activate LED strip animations, sound on Sound Board
   5 *found micropyton library (https://github.com/kfricke/micropython-us100)
   6 that will use.
   7 downloaded into /home/pi/Desktop/microPythonProjects/sensorLib
   8 created directory inside microPythonProjects>sensoryWall
   9 have us100 test script to print distance and verify it works. IT DOES!!

  11 <<<<<<< HEAD
  12 =======
  13 fancy LEDs
  14 --short pin is ground, long needs power and resistor
  15
  16 will test distance sensor sensing distance>turning on LED
  17 ----see distanceTest.py
  18
  19 !!need to clearly define operating distance!!

  22 decided to test code for PDM mic and is31fl3741 LED board, separately
  23 will most likely have to run circuitpython for this feature, currently
  24 testing on KB2040 (got 1 free in order) hoping to reduce total number of
  25 wires
  26 can animate LEDs
  27 using Adafruit guides, set up/tested mic and got values (but no sound.file).
  28 also, have set up NFS mount to allow for easier backup/access to backuped file

  31 got the LED matrix animation working, using a project pack from Adafruit.
  32 brougth to work, along with breadboarded us100 and LEDs. Individuals really
  33 liked. Did enjoy toggling matrix on/off, and playing with distance sensor
  34 to light up LEDs. Put toggle switch on clock line of PDM mic, allowing
  35 on/off toggle

  37 8/5/23
  38 fully built 5v led strip controller (animated LED strip, us-100, arcade
  39 button), coded so that light is off unless close enough to activate, or
  40 button pressed. Did build n00ds web, using randomint for time on/off on
  41 strands. got 12v tower light running, burned pico out with 12v short into
  42 it from light/hair bridging pins. NEED TO USE KAPTON TAPE!!!!!
  43 may throw 2 pico's in, 1 to replace the one i killed, 1 to make another
  44 12v controller.
  45
  46 sound board was replaced, is working at this time. Can control via GPIO
  47 by pulling pins low. no need to add mcu to control this device, but if
  48 tying lines, need common ground. then just set that pin as output, pull
  49 high/low as needed, control via button press/trigger event
