Build your server offline monitor device under $7
As I said on my previous post, this is a small tutorial on creating a device (beeper) which can alert you on server/website downtime.
- Wires/jumper cables
- Piezo buzzer
I wanted to add more components like LCD and buzzer amplifier but I cannot find those things around me and it's night. I'll update the tutorial when I can.
Connect the D2 pin to positive of buzzer and Ground to negative.
And upload this:
And host this somewhere
- Add a silence button
- Use a Esp-01 instead
- LCD with more information like Server detail
- RTC module to control buzzer according to time
- Build an enclosing for it
P.S. This is a very simple project but was fun to do. I'm still learning electronics so would hopefully be able to create a fairly useful one soon.
P.S.S. There is a lot of logging to serial in code as it's a modified script of examples. I haven't removed them since it's still uncomplete.
