This is essentially a wifi enabled digital clock with buzzer. This will not work as expected without a backend running on a x86 machine. Since wifi connected to backend, i've made an api to configure/show text or ring buzzer. so any self-hosted application can take advantage of this, like a cpu temp/freq monitor, or attach to home assistant, etc.
This is a casual project just for the fun of using esp32 and MAX2719 ic from datasheet. Yup, i haven't used MAX2719 library to control the display, i used the datasheet to craete api of my own. It's cool to try out for the 1st time.
- The self-hosted backend is used for
- Time synchronization
- text to be displayed
- start/stop sound ( yea, alarms can't be stored in the clock, but in the backend )
- brightness control
- Frontend (Web, nextjs preferrably)
- implement alarm in backend
- add LDR to hardware, auto adjust brightness and report luminance data to homeassistant.
