We are combining Water sensor and passive buzzer. We are sounding an alarm based on water detected by the water sensor. #define c 3830 // 261 Hz #define d 3400 // 294 Hz #define e 3038 // 329 Hz #define f 2864 // 349 Hz #define g 2550 // 392…
#include <Servo.h> Servo servo; // Arduino pin numbers const int SW_pin = 2; // digital pin connected to switch output const int X_pin = 0; // analog pin connected to X output const int Y_pin = 1; // analog pin connected to Y output int servorotate = 0; int xvalue…
The circuit for this lesson is simple, we use a passive buzzer. The negative of the buzzer goes to the GND and positive goes to PIN 9 on the arduino. int buzzerPIN = 9; #define c 261 #define d 294 #define e 329 #define f 349 #define g 392…
A simple program to read the code that is received by any Infrared remote control. #include <IRremote.h> const int RECV_PIN = 7; IRrecv irrecv(RECV_PIN); decode_results results; void setup(){ Serial.begin(9600); irrecv.enableIRIn(); irrecv.blink13(true); } void loop(){ if (irrecv.decode(&results)){ Serial.println(results.value, HEX); irrecv.resume(); } } A simple modification on this code with a if…
This is a simple sound sensor experiment. That takes a sound to turn on or turn off an LED. Here we use digital output from the sensor to measure the presence of the sound. The DO will goto pin 2 in arduino. LED’s +ve is connected to 4. Other circuit…
const int trigPin = 9; const int echoPin = 10; // defines variables long duration; int distance; void setup() { pinMode(trigPin, OUTPUT); // Sets the trigPin as an Output pinMode(echoPin, INPUT); // Sets the echoPin as an Input Serial.begin(9600); // Starts the serial communication } void loop() { // Clears…
DHT11 needs a simple circuit. Refer the above diagram. The code is below #define DHT11PIN 7 dht11 DHT11; void setup() { Serial.begin(9600); } void loop() { Serial.println(); int chk = DHT11.read(DHT11PIN); Serial.print(“Humidity (%): “); Serial.println((float)DHT11.humidity, 2); Serial.print(“Temperature (C): “); Serial.println((float)DHT11.temperature, 2); delay(2000); } To change DHT11 temperature to Fahrenheit use…
