 Customize the application for your specific settings by editing [src/constants.h](src/constants.h).
 
-- `WIFI_MODE` (0 - AP mode, 1 - STA mode)
-- `WIFI_SSID` and `WIFI_PASSWORD`
-- `TIME_ZONE` (hour offset for correct work of Night Mode)
-- `MDNS_NAME` (mDNS for local network, default address [http://esp_lamp.local](http://esp_lamp.local))
-- `LED_PIN` and `LED_TYPE` for your LED strip/matrix configuration
-- `WIDTH` and `HEIGHT` for your configuration (count of LEDs for vertical and horizontal)
-- `MATRIX_VOLTAGE` and `CURRENT_LIMIT` for your specific power supply
