ESP8266 + Firebase + OTA moodlight - (nodeMCU)

This is my custom moodlight project.
I was using ESP01-S from ESP8266 family, LED RGB, Firebase for controlling over internet (soon application will be made), OTA for updating firmware over wifi. It is powered by phone chargher which is connected to AMS1117-3.3 voltage regulator to keep safe voltage for ESP providing up to 1A.
Many more ideas arised.
