🔧 What is Arduino?
Arduino is an open-source electronics platform based on easy-to-use hardware and software. The Arduino Uno is the most popular board used for learning electronics and building creative projects, from robots to automation systems.
⚙️ How Arduino Works
Arduino works like a mini-computer. It takes input from sensors, processes the information via code, and sends output signals to devices like LEDs, motors, buzzers, etc. Coding is done in the Arduino IDE and uploaded via USB.
📍 Arduino Uno Pinout
Here’s a breakdown of the Arduino Uno pinout and their uses:
- Digital Pins (0–13): Input/Output operations, PWM supported on 3, 5, 6, 9, 10, 11
- Analog Pins (A0–A5): Read analog input signals (e.g., sensors)
- Power Pins: 5V, 3.3V, GND, Vin for external power supply
- AREF: Analog reference voltage
- RESET: Resets the board
🧩 Useful Components for Arduino Projects
Component | Use |
---|---|
Breadboard | Build circuits without soldering |
Jumper Wires | Connections between modules |
LEDs & Resistors | Basic outputs |
Ultrasonic Sensor | Measure distance |
IR Sensor | Obstacle detection |
Servo Motor | Rotational control |
Relay Module | Control appliances |
OLED Display | Visual feedback |
💡 Arduino Uno Project Example: Blinking LED
This is the simplest project to test if your Arduino works:
- Connect an LED to pin 13 with a 220-ohm resistor
- Upload the below code in Arduino IDE:
void setup() { pinMode(13, OUTPUT); } void loop() { digitalWrite(13, HIGH); delay(1000); digitalWrite(13, LOW); delay(1000); }
