//ESP8266-01 (blue) got too little storage space to work with all features of WLED. To use it, you must use ESP8266 Arduino Core v2.3.0 and the setting 512K(64K SPIFFS).
//ESP8266-01 (black) has 1MB flash and can thus fit the whole program. Use 1M(64K SPIFFS).
//Uncomment some of the following lines to disable features to compile for ESP8266-01 (max flash size 434kB):
//You are required to disable over-the-air updates:
//#define WLED_DISABLE_OTA
//You need to choose 1-2 of these features to disable:
//#define WLED_DISABLE_ALEXA
//#define WLED_DISABLE_BLYNK
//#define WLED_DISABLE_CRONIXIE
//#define WLED_DISABLE_HUESYNC
//#define WLED_DISABLE_INFRARED //there is no pin left for this on ESP8266-01
//#define WLED_DISABLE_MOBILE_UI
#define WLED_DISABLE_FILESYSTEM //SPIFFS is not used by any WLED feature yet
//#define WLED_ENABLE_FS_SERVING //Enable sending html file from SPIFFS before serving progmem version
//#define WLED_ENABLE_FS_EDITOR //enable /edit page for editing SPIFFS content. Will also be disabled with OTA lock
//to toggle usb serial debug (un)comment the following line
