2.4 Uploading the Sketch
Now that we have configured the Sketch to our needs we can Upload it to the D1 Mini
In Arduino IDE go to Tools > Board and select your Device. In our case it is the LOLIN(WEMOS)D1 R2 & mini
Now go to Tools > Port select your USB port where you have connected the D1 Mini to. In our case it is COM 5
In Arduino IDE go to Sketch > Upload
If it fails to connect, try changing the COM Port.
If all was successfull the Console output should look simulare to this
Executable segment sizes:
IROM : 367992 - code in flash (default or ICACHE_FLASH_ATTR)
IRAM : 27928 / 32768 - code in IRAM (ICACHE_RAM_ATTR, ISRs...)
DATA : 1532 ) - initialized variables (global, static) in RAM/HEAP
RODATA : 4304 ) / 81920 - constants (global, static) in RAM/HEAP
BSS : 37104 ) - zeroed variables (global, static) in RAM/HEAP
Sketch uses 401756 bytes (38%) of program storage space. Maximum is 1044464 bytes.
Global variables use 42940 bytes (52%) of dynamic memory, leaving 38980 bytes for local variables. Maximum is 81920 bytes.

If not you may have missed a Step. If your D1 Mini is already powerd and connected to the LED Strip it should be light up in a Rainbow mode.
