🛠️ Setting Up Your First Arduino Project

Starting with Arduino is refreshingly simple:

1️⃣ Start by downloading the Arduino IDE from the official source. 2️⃣ Connect your Arduino UNO to your PC using a standard USB Type-B cable.
3️⃣ From the Tools menu, choose your board model and the right COM port.
4️⃣ Try uploading the famous Blink sketch — a simple program that flashes the onboard LED on pin 13.

And just like that, you’ve joined the maker community!

⚡ Working with Digital & Analog Pins

🔸 Digital Pins

These pins can switch between HIGH (5V) and LOW (0V), making them ideal for turning LEDs on/off or reading button presses.

pinMode(8, OUTPUT);
digitalWrite(8, HIGH);

🔸 Analog Pins

Perfect for reading values from sensors like potentiometers or temperature sensors. The values range from 0 to 1023, representing 0V to 5V.

int reading = analogRead(A0);

🎛️ Understanding PWM: Smooth Control of LEDs & Motors

PWM (Pulse Width Modulation) lets you simulate analog output using digital pins. On the UNO, pins 3, 5, 6, 9, 10, and 11 support PWM.

Example for 50% LED brightness:

analogWrite(9, 127);

📡 Communicating with Other Devices

Your Arduino UNO can talk to other devices using:

• SPI (Serial Peripheral Interface) — Ideal for SD card modules, RFID readers, etc.
• I2C (Inter-Integrated Circuit) — Perfect for connecting multiple sensors and displays with just 2 wires.

🚨 Interrupts: Instant Reaction Mechanism

Interrupts let your Arduino pause what it’s doing and handle important events immediately.

Example:

attachInterrupt(digitalPinToInterrupt(2), myFunction, CHANGE);

Great for handling things like emergency stop buttons or motion detection alerts.

💾 Smart Memory Usage Tips

With just 2 KB of SRAM, efficiency matters:

• Use smaller data types like byte or uint8_t where possible.
• Avoid unnecessary global variables.
• Prefer char arrays over String objects for text handling.
• Be cautious with dynamic memory allocation.

Monitor your program’s memory footprint using the Serial Monitor and sizeof().
