LED blink project using arduino uno - by "VISION36":

Image
 IN THIS BLOG WE WILL BE MAKING A BASIC ARDUINO PROJECT TO GET OURSELVES FAMILIAR WITH ARDUINO MICRO_CONTROLLERS AND IDE WITH THIS BLOG *COM0PONENTS : ARDUINO UNO LED connect pin 13 to positive of led and connect gnd to negative of led  OPEN ARDUINO IDE AND UPLOAD THE CODE GIVEN BELOW : void setup() {  pinMode(13 , OUTPUT); } void loop() { digitalWrite(13 , HIGH); delay(500); analogWrite(13 , 50); digitalWrite(13, LOW); delay(500); } now the led should be blinking right now ,,

Temperature and humidity monitoring by vision36 ,,, dht 11 sensor .

 This is a project in which we will be using arduino and dht 11 temperature and humidity sensor ... so u can view the temperature and humidity in the serial monitor ,,,, LETS GET STARTED  * ARDUINO UNO  *DHT 11 TEMPERATURE AND HUMIDITY SENSOR  IN THIS PROJECT WE WILL BE USING "UNO" , "DHT 11" , " ARDUINO IDE" , AND SOME JUMPER WIRES ,,,  CONNECT PIN NUMBER 2 TO THE DATA PIN ON THE DHT 11 [signal] CONNECT 5V PIN TO THE VCC OF DHT11 SENSOR  [ voltage (or) power ] CONNECT GND TO THE GND PIN ON DHT11 SENSOR [ ground ] now upload the code given below in the arduino ide  CODE :  #include "DHT.h" #define DHTPIN 2     #define DHTTYPE DHT11   DHT dht(DHTPIN, DHTTYPE); void setup() {   Serial.begin(9600);   Serial.println(F("DHTxx test!"));   dht.begin(); } void loop() {      delay(2000);      float h = dht.readHumidity();     float t = dht.readTemperature();      float f = dht.readTemperature(true);      if (isnan(h) || isnan(t) || isnan(f)) {
