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.
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)
Materials
- Tessel
- Relay Module
- Alarm light
Tools
- Screwdriver
- Wire strippers (scissors work, if you’re careful)
- Computer for programming
