  • timeBuzzer app may be running (MIDI port is shared)

Script

Single CLI: scripts/buzzer_led.py

Color commands

python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py color red
python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py color --hex "#FF8800"
python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py rgb 255 100 0

python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py pulse blue --bpm 30 --seconds 5
python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py strobe red --count 5 --interval 0.15
python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py rainbow --seconds 5
python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py fade warm --seconds 2

Status signals (parallel to hue skill)

python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py signal success
python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py signal thinking --seconds 5

Per-segment control

python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py segment 0 255 0 0   # seg 0 red
python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py segment 1 0 255 0   # seg 1 green
python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py segment 2 0 0 255   # seg 2 blue

Protocol details

  • USB MIDI device (vendor 0x16D0, product 0x1170)
  • Sends/receives MIDI CC on channel 12 (status byte 187/0xBB)
  • LED output: CC 70-78 for 3 segments x 3 channels (R, G, B)
  • Values: 0-127 (half of standard 0-255 RGB)
  • The timeBuzzer app controls LED based on active project color; this script overrides it directly

Syncing with Hue

Use the same signal vocabulary as the hue skill. Example combined command:

python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py signal success &
python3 ~/.claude/skills/hue/scripts/hue.py signal success --group 1
