1 Overview
- pinMode()
- digitalWrite()
- digitalRead()
2 Warning
Noduino use the ESP8266/ESP8285 SoC.
They are all 3.3V.
So:
- HIGH is 3.3V
- LOW is 0V
3 Examples
Use the pin D5 to output a square wave:
#include "noduino.h"
void setup()
{
pinMode(D5, OUTPUT); // set D5 to output mode
digitalWrite(D5, LOW);
}
void loop()
{
digitalWrite(D5, HIGH); // ouput high level
delay(1000); // delay 1000ms
digitalWrite(D5, LOW); // output low level
delay(1000);
}
