Getting Start with NUTTYFI- An IoT Device Examples

Fundamental Requirements:

To Start with NUTTYFI, You have to NUTTYFI IOT Device & FTDI USB to UART Bridge.

After that Connect NUTTYFI to your Computer using FTDI USB to UART Bridge & got to tools -> boards-> NodeMCU 1.0(ESP-12E Module & Select the Port like COM3.

after that copy these code (codes given below) to your arduino IDE & compile & upload to NUTTYFI & all done.

Examples- 

  • How to Blink LED using NUTTYFI?
/**************************************NUTTYFI****************************/
// connect LED Positive pin at D6 of NUTTYFI. Connect Negative pin of LED to GND at NUTTYFI.
const int led = D6;
void setup() {
pinMode(led, OUTPUT); // initialize digital pin 'led' as an output.
} 
// the loop function runs over and over again forever 
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}

// initialize the library with the numbers of the interface pins

void setup() {
// set up the LCD's number of columns and rows:
lcd.begin(16, 2);
// Set the cursor
lcd.setCursor(0, 0);
// Print a message to the LCD.
lcd.print("Hi! Welcome");
}

lcd.print("to NUTTYFI");
