The wake-up light emulates alarm clocks like Philips' Wake-Up Light.
This is based upon Frans van Buul's Wake-up Light. I liked that it had a web gui to set alarms, but I wanted a real alarm clock, not the ceiling mounted light.
Starting from the light and web ui, these were added:
- Four digit 7-segment LED display (TM1637)
- Adaptive intensity for the display
- I also wanted the web interface to have more of the feel of the standard Android alarm clock with multiple alarms
- Password required when changing alarms
- Easy Wifi set-up: no hard coded credentials
- Also added was a multi-function button:
- turn off the alarm when activated
- cycle through 3 light intensities
- startup as an AP and WifiManager when held down at power-up
- NeoPixel or PWM as a light source, PWM can be inverted or non-inverted
- Plays mp3 file repeatedly when the alarm is active (Adafruit or Sparkfun MAX98357)
With all the added functionality, the number of exposed IO pins on an ESP-01 is not enough. I used an Olimex MOD-WIFI-ESP8266, but any ESP-12 variant would probably do.
