Noduino Digital Pin
来自Jack's Lab
1 Overview
- pinMode()
- digitalWrite()
- digitalRead()
2 Warning
Noduino use the ESP8266/ESP8285 SoC.
They are all 3.3V power supply.
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); }
