2. Code & Interface Design¶
Libraries¶
Many libraries took part of coding this project. The main ones that were primordial are
- TIME
- ESP8266 WIFI
- MOONPHASER
- FAST LED
- ESP8266WebServer
- ESP_EEPROM
Code Logic¶
The logic of the code was as follows:
- Once motion is detected from motion sensor, turn on light and connect to internet through WI-FI.
- Retrieve time through NTP and link it to current angle of the moon and lit surface.
- Connect the html page on the local server of the ESP8266 with button input.
- Define which moon phase it would belong to, and apply a function that defines which LEDs of the Neopixels. are lit & which colour.
- Everytime the motion sensor
-
Once motion is detected, activate local server.
-
If button on local server is pushed, retrieve date and save in eeprom while adding 25 days in epoch time to the value.
-
We use eeprom so that the value is not wiped once the lamp is off.
-
Everytime the motion sensor senses motion, it checks if the epoch value saved is smaller than current time. If so, it changes the mode of the Neopixels.
