Volcanic Rock Gym RGB LED Training Board

This project is to build climbing trainer board for Volcanic Rock Gym

Hardware:

• Raspi Zero-W
• WS2811 RGB led lighting string
• 1000uF Capacitor for smoothing power inrush to Ws2811
• IN4001 Diode
• 3.3v to 5v logic level converter for raspi to WS2811 communications
• Custom interface board
• 6 x Arcade buttons (N.O.)

Software libraries:

• Adafruit NeoPixel libraries

Function Description

• The end product will be a climbing training board with various routines tied to buttons.
• Press button 1, initiate routine 1, button 2 = routine 2 etc.
• There will be one button which acts as a start/stop/reset button.
• This button acts as a softswitch enabling or diabling the other buttons. The main python script is always running.
• There are configuration files associated with this script:

Each climbing pattern has its own configuration file with the following format:

ROW(0-8) LED#(0-2) RED(0-255) GREEN(0-255) BLUE(0-255)

example pattern file:

  0 2 255 0 0
  1 0 0 0 255
  2 2 255 0 0
  3 0 0 0 255

• The main file reads in this file into a list of lists which is then iterated through turning on each LED specified to the specified color.
• Multiple LEDS in each row can be lit

0 2 255 0 0
0 0 0 0 255
2 2 255 0 0
2 0 0 0 255

Script Launcher

• Python script is automatically launched using the systemd method.
• RGB_Climber_service.service is created (see file for details)
  • ExecStart must be modified to match path of python script
  • ExecStart=/usr/bin/python /home/pi/path_to_script_dir/Main_RGB_Trainer.py
• Place file into /lib/systemd/system/
• service must then be enabled:
  • sudo systemctl daemon-reload
  • sudo systemctl enable sample.service
• Status can be checked via:
  • sudo systemctl status RGB_Climber_service.service -l
• Status can also be start/stopped via the same method:
  • sudo systemctl start RGB_Climber_service.service -l
  • sudo systemctl stop RGB_Climber_service.service -l
