Blink led light using Arduino r3

Here's a simple guide to get you started with a blinking LED project using Arduino:

Components Needed
- Arduino Board (e.g., Arduino Uno)
- LED
- Resistor (220-ohm or suitable for your LED)
- Breadboard and jumper wires

Circuit Setup
1. Connect the LED's anode (long leg) to a digital pin on the Arduino (e.g., pin 13).
2. Connect the LED's cathode (short leg) to one end of the resistor.
3. Connect the other end of the resistor to a GND pin on the Arduino.

Code
void setup() {
  pinMode(13, OUTPUT); // Set pin 13 as output
}

void loop() {
  digitalWrite(13, HIGH); // Turn LED on
  delay(1000); // Wait 1 second
  digitalWrite(13, LOW); // Turn LED off
  delay(1000); // Wait 1 second
}
How it Works
1. The `setup()` function sets the LED pin as an output.
2. The `loop()` function repeatedly turns the LED on and off with a 1-second delay between each state change.

Upload and Enjoy!
Upload the code to your Arduino board, and the LED should start blinking! 😊

Temperature sensor using Arduino Uno

A temperature sensor project with Arduino can be useful for monitoring temperature in various applications. Here's a simple guide: Components Needed - Arduino Board (e.g., Arduino Uno) - Temperature Sensor (e.g., LM35 or DS18B20) - Breadboard and jumper wires Circuit Setup 1. Connect the temperature sensor to the Arduino:     - VCC to 5V pin     - GND to GND pin     - Signal pin to an analog input pin (e.g., A0) Code For LM35: const int tempPin = A0; void setup() {   Serial.begin(9600); } void loop() {   int tempValue = analogRead(tempPin);   float temperature = (tempValue * 5.0 / 1024.0) * 100;   Serial.print("Temperature: ");   Serial.print(temperature);   Serial.println("°C");   delay(1000); } For DS18B20: #include <OneWire.h> #include <DallasTemperature.h> const int tempPin = 2; OneWire oneWire(tempPin); DallasTemperature sensors(&oneWire); void setup() {   Serial.begin(9600);   sensors.begin(...

Ir sensor using Arduino

An IR sensor project with Arduino Uno can be used for obstacle detection, line following, or remote control applications. Here's a simple guide: Components Needed - Arduino Uno - IR Sensor Module (e.g., VL53L0X or simple IR sensor) - Breadboard and jumper wires - LED (optional) Circuit Setup 1. Connect the IR sensor module to the Arduino:     - VCC to 5V pin     - GND to GND pin     - Signal pin to a digital pin (e.g., pin 2) Code For simple IR sensor: const int irPin = 2; void setup() {   pinMode(irPin, INPUT);   Serial.begin(9600); } void loop() {   int irValue = digitalRead(irPin);   Serial.println(irValue);   delay(100); } For obstacle detection with LED: const int irPin = 2; const int ledPin = 13; void setup() {   pinMode(irPin, INPUT);   pinMode(ledPin, OUTPUT); } void loop() {   int irValue = digitalRead(irPin);   if (irValue == LOW) {     digitalWrite(ledPin, HIGH); // Obstacle detected   }...
