/*************************************************************
* Project OnLight V1.0
* Description: OnLight is a smart light connected to the Wi-Fi. 
It can be controlled via the Blynk app. Various functions are 
already preprogrammed, e.g. four light settings, color picker 
and strobe light. The OnLight-Case is 3D printed and can be screwed into 
E-27 sockets or on self-developed mounts.
