			\| align="light" \| '''ICSP (In-Circuit Serial Programming) Header'''
			the AVR, an Arduino micro-program header consisting of MOSI, MISO, SCK, RESET, VCC, and GND.
			It is often called the SPI (serial peripheral interface) and can be considered an "extension" of the output.
			In fact, slave the output devices to the SPI bus host.
			When connecting to PC, program the firmware to ATMEGA328P-PU.

			\| align="light" \| '''Power LED Indicator'''
			Powering the Arduino, LED on means that your circuit board is correctly powered on.
			If LED is off, connection is wrong.

			\| align="light" \| '''AREF '''
			Reference voltage (0-5V) for analog inputs. Used with [https://www.arduino.cc/reference/en/language/functions/analog-io/analogreference/ analogReference()].
			Configures the reference voltage used for analog input (i.e. the value used as the top of the input range).
