ICT 8 (ADRUINO BOARD)

• Power USB - arduino board can be powered by using the USB cable from computer. Connect usb cable to the usb connection
• Power (Barrel Jack) - Arduino board can be powered directly from the AC mains power supply by connecting it to the...
• Voltage Regulator - control the voltage given to the arduino board that stabilize the DC voltages used by the processor and other elements.
• Crystal Oscillator - helps Arduino in dealing with time issues
• Arduino reset - connect an external reset button to the arduino pin labeled reset
• Analog pins - the arduino uno board has six analog input pins. these pins can read the signal from an analoh sensore lik the himidity sensor or temperature sensor and convert it into a digital value that can be read by the microprocessor
• Main microcontroller - each arduino board has it's own, the arduino is slightly different from board to board. It is usually of the ATMEL company.
• ICSP pin (In Circuit Serial Programming Pin) - often reffereed to as an SPI (Serial Peripheral Interface) which could be considered as an "expansion" of the output.
• Power LED indicator - this LED should light up when you plug your Arduino into a power source to indicate that your board is powered up correctly.
• AREF - stands for Analog Reference, sometimes used to set an external reference voltage
• TX (transmit) and RX (receive) LEDs - appear in two places on the arduino UNO board
