Portable Reaction Trainer

Project Plan

ACTION ITEMS:

  • SD card - leverage Adafruit.IO?
  • Design Board
  • Countdown & UX Shift to new board

COMPLETE:

  • Raspberry Pi Circuit Python install - complete
  • Install Button Switch Circuit - complete
  • Dev Button Switch Count - complete
  • Dev Button/Switch/LED Sync - complete
  • Install Timer Circuit
  • Install Button Counter Circuit
  • Dev Timer Countdown to LED
  • Dev Button Counter to LED
  • Install NeoPixel libraries
  • Install extension pins
  • Install LED libraries

NOTES & LEARNINGS:

  • Hardware/Software Build

    • Need minimum 5V for LED to be bright enough for reactions

  • Test for NeoPixel Chip

    • For speed, using the Feather M4 developed for the LAX Trainer
    • 5V feed from RPi & digital driven by Feather
    • 8/6 - seems like a short with the circuit, will need to redo chips
      1. Try one at a time (leverage red 255,0,0) - driving 3 separate outputs for R,G,B channels
      2. Flux
      3. New Soldering Paste

  • Library versions for M0

  • UF2 installation mode

  • I2C Matrix LED address definition with board (0x70 + A0, A1, A2)

  • Simple button switch IO

  • Metro M4 Grand Central processor
