UNOATmega328P: The 8-bit AVR microcontroller that runs your sketch (16 MHz, 32 KB flash, 2 KB RAM).ATmega328PUSB-B: USB connection for uploading sketches and for the Serial Monitor. Also powers the board (5 V).DC jack: Barrel jack for 7–12 V from a battery pack or adapter (centre positive).ATmega16U2: Converts USB to serial for uploads and Serial.print().RESET: Restarts your sketch from the beginning (setup() runs again).L (D13): Built-in LED connected to pin 13 (LED_BUILTIN).ON: Power indicator.5 V regulator: Turns 7–12 V from VIN/jack into a steady 5 V.16 MHz: Clock source: the microcontroller runs 16 million cycles per second.ICSP: In-circuit programming header (SPI). Used to burn a bootloader; not needed for normal uploads.

GPIO Pin Monitor

No active GPIO pins configured yet. Call pinMode() in setup().

Serial Monitor
