Website Down Alarm

If your website goes down, you want to be the first to know. Make it obvious when there’s a problem by hooking up a big alarm light to a Tessel, which will ping your website every few seconds to check for trouble.

Website Down Alarm

Light patterns

  • Continuously off: all is well
  • Continuously on: website being monitored is down
  • Two-second bursts (on or off): system error; monitoring isn’t working (reset the Tessel)



  • Screwdriver
  • Wire strippers (scissors work, if you’re careful)
  • Computer for programming
