LED

RevivingIndia Meena bazar, Patna, India

What is LED ? LED stands for Light Emitting Diode. It's a semiconductor device that emits light when an electric current passes through it. Things to do Connect Annode (+) part of Led to Digital pin of Arduino i.e 13 Connect Cathode(-) part of Led to Groundpin of Arduino Interfacing Diagram Interface a microcontroller, like an Arduino, with external components, you typically use a combination of wiring and programming. Here's a short overview of the basic steps: Identify the components you want to interface with the Arduino, such as sensors, LEDs, motors, etc. Determine the electrical requirements of these components (voltage, current, signal levels). Connect the components to the appropriate pins on the Arduino board using jumper wires, breadboard, or soldering depending on your setup. Write a program (sketch) in the Arduino IDE to control and interact with these components. This involves configuring pins, reading sensor data, and sending signals…

RGB

What is RGB? RGB, short for Red Green Blue, is a color model used in digital imaging to represent colors on screens. It combines different intensities of red, green, and blue light to create various colors. How to use RGB Interior Lighting Art Projects Signage and Displays Gaming Stage Lighting Automotive Lighting Home Automation Prototyping Components Required: Microcontroller (Arduino) RGB Jumper Wires USB Cable Working Interface: The RGB LED is connected to the Arduino via jump wires on a breadboard. Arduino code, controls the LED's colors based on input, like touch or proximity sensors Example Code: void setup() { pinMode(8,OUTPUT); // Red led pin pinMode(9,OUTPUT); // Green led pin pinMode(10,OUTPUT); // Blue led pin } void loop() { digitalWrite(8,HIGH); // Red led ON digitalWrite(9,LOW);  // Green led OFF digitalWrite(10,LOW); // Blue led OFF delay(1000); digitalWrite(8,LOW);  // Red led ON digitalWrite(9,HIGH);  // Green led OFF digitalWrite(10,LOW);  // Blue led OFF delay(1000);…

IR Sensor

RevivingIndia Meena bazar, Patna, India

What is an IR Sensor? IR sensor with Arduino and interface it with some components like an LED and a buzzer. We'll make a setup where the LED lights up and the buzzer sounds when motion is detected by the IR sensor. Components Needed. 1.Arduino board 2.IR sensor module 3.LED 4.Buzzer 5.Jumper wires Wiring Connections: Connect the VCC pin of the IR sensor module to the 5V pin of the Arduino. Connect the GND pin of the IR sensor module to the GND pin of the Arduino. Connect the OUT pin of the IR sensor module to digital pin 2 of the Arduino. Connect the positive (anode) leg of the LED to digital pin 3 of the Arduino through a current-limiting resistor (220-330 ohms). Connect the negative (cathode) leg of the LED to the GND pin of the Arduino. Connect one terminal of the buzzer to digital pin 4 of…
