Hardware Connection
Plu g the Crow tail-LED to the D1 port on NodeM CU by a 3pin Crow tail-C a ble
as followin g.
Open the LuaLoader. Clic k the butto n in the GP IO funct ion area, choose GP IO5
port, set it as Out put mo de, click ”1” the LED will light up, cl i ck “0 ” the LED will
light of f.
Also, we can downl oad the code to the NodeMCU. Copy the bellow code and
paste it to LuaEdi tor, then save the file an d named it “init.lua ”
