Esp8266 Arduino programming example GPIO input and output

GPIO Input and output

This example will demonstrate how to pass GPIO Input and output function control LED.

1、GPIO Input and output control

1）GPIO Mode setting

By function pinMode Can be GPIO Set to input or output mode ：

pinMode(pin,INPUT); //  Set to input mode 
pinMode(pin,OUTPUT); //  Set to output mode 

2）GPIO State settings

By function digitalWrite Function can control GPIO The state of ：
