Control Devices through Arduino and Bolt IoT Module
Here we take an example of a Led to control it through Arduino and Bolt IoT Module
Component required
- Arduino Uno
- Bolt IoT Module
- Led
- Jumper Wire
Arduino Code
#include <BoltIoT-Arduino-Helper.h> //Include Bolt-Arduino-Helper Library
#define led 6 //Pin declaration for led
String command = ""; //variable for storing command
// function for Controlling Led
String on(String *data) {
command = "ON";
led_on();
return "Led:ON";
Serial.println("Led is now turned on");
}
// function for Controlling Led
String off(String *data) {
command = "OFF";
led_off();
return "Led:OFF";
Serial.println("Led is now turned off");
}
void setup() {
// put your setup code here
pinMode(led,OUTPUT); // pinMode decide input or output type
boltiot.begin(Serial); //here hardware serial is used
Serial.begin(9600); //baud rate for transsmit and receive data
boltiot.setCommandString("ON",on);
boltiot.setCommandString("OFF",off);
}
void loop() {
// put your main code here, to run repeatedly:
boltiot.handleCommand(); //Bolt command controll
}
void led_on(){
digitalWrite(led, HIGH);
}
void led_off(){
digitalWrite(led,LOW);
}
