Periodic fan. Computer fan is turned ON/OFF on regular intervals.
- Improve interface:
- Make clicks for pause intervals and fan speed as consistent as possible (click, dbl click, long click)
- Small display (ESP32-C3 with built-in display or separate display) or LED diodes
- Make final design for the device:
- How to turn off device: switch on separate USB C connector or make ESP go to deep sleep
- Choose 2 buttons for changing speed and pause interval
| Button | Click | DblClick | LongClick |
|---|---|---|---|
| interval/pause | inc pause | dec pause | no pause (fan continuously works) |
| pwm/speed | inc speed | dec speed | max speed and no pause |
- If speed or pause is max/min - inc/dec doesn't do anything.
- Display will turn off automatically. If display is off, first click turns it on. Maybe ESP should go to sleep and should start if some button is pressed.
