Arduino Introduction
The Arduino is an open-source microcontroller board based for controlling Hardware components. Structure Parts Name USB: can be used for both power and communication with the IDE Barrel Jack: used for power supply Voltage Regulator: regulates and stabilises the input and output voltages Crystal Oscillator: keeps track of time and regulates processor frequency Reset Pin: can be used to reset the Arduino Uno 3.3V pin: can be used as a 3.3V output 5V pin: can be used as a 5V output GND pin: can be used to ground the circuit Vin pin: can be used to supply power to the board Analog pins(A0-A5): can be used to read analog signals to the board Microcontroller(ATMega328): the processing and logical unit of the board ICSP pin: a programming header on the board also called SPI Power indicator LED: indicates the power status of the board RX and TX LEDs: receive(RX) and transmit(TX) LEDs, blink when sending or receiving serial data respectively Digital I/O...
