Verified summary

Physical GitHub Actions build-status indicator using an Arduino MKR WiFi 1010 and four LEDs.

Problem or experiment question

Can a desk-mounted LED device reflect the latest GitHub workflow status for a configured repository?

What was actually built

  • Wi-Fi connection and GitHub API workflow-run polling
  • State mapping for queued, running, success, and failure
  • Four LED outputs with manual JSON/string extraction
  • Repository-specific configuration in firmware

Architecture or workflow

  • Network layer: Wi-Fi and HTTPS to GitHub API
  • Parse layer: manual extraction of workflow state
  • Output layer: four LEDs representing CI status

Important technical decisions

  • Traffic-semaphore metaphor makes status glanceable
  • Polling chosen over webhooks for embedded simplicity
  • Fixed repository configuration suits a single-purpose desk device

Known limitations

  • Hardcoded organization/repository configuration
  • Aggressive polling interval for reusable production use
  • Manual response parsing is brittle
  • Token storage on device needs careful handling
