Simple clock uses connected to Wifi, NTP and TimeZone
Parts required
- NodeMCU v3 board (lolin variant for the size) like this one
- A dot matrix led like this one
- M3 15mm long screws
Code and instructions are in GitHub here (I'll also add the STL files there soon)
Tools
- a computer
- an USB cable to plug the NodeMCU
- a create a screw thread using a 3mm tap
Instructions
Electronic
Follow the instructions inside the git repository (do not forget to add your settings for Wifi and timezone)
Assembly
- Create a screw thread using a 3mm tap for all the prepared screw locations you want to use
- Connect electronic and test (before assembling)
- Assemble
Improvement
- a better closing method (rather than creating a screw thread with a tap)
- a more dynamic (at runtime and not at build time) way to configure Wifi and timezone
