Arduino Week 8 Lesson

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…

Arduino Week 7 Lesson

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…

DHT11 Week 5 Class

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…
