3 Warning

Noduino use the ESP8266/ESP8285 SoC.

They are all 3.3V power supply.

So:

• HIGH is 3.3V
• LOW is 0V

4 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);
}

You can try the example in noduino-sdk/examples/noduino/blink
