Tiny Components on an Arduino Board & Their Functions
An Arduino board consists of several small but essential components that enable its functionality:
🔹 MCU (Microcontroller): Brain of the board
🔹 Vin, 5V, 3.3V, GND: Power supply
🔹 I/O Pins (Digital & Analog): Read sensors, control outputs
🔹 PWM Pins: Simulate analog output (motors, LEDs)
🔹 USB Port: Programming & power
🔹 RST (Reset Button): Restart the board
🔹 Oscillator: Maintains timing & clock functions
🔹 Regulator: Manages voltage supply
