To control the voltage provided to the Arduino board, as well as to stabilize the DC voltage used by the processor and other components.Ĭonvert an external input DC7-12V voltage into DC 5V, then switch DC 5V to the processor and other components.Īrduino board can be supplied with an external power DC7-12V from the DC power jack. It tells us that the frequency is 16,000,000 Hertz or 16MHz. The number printed on the top of the Arduino crystal is 16.000H9H. How does Arduino calculate time? by using a crystal oscillator.

When Arduino board communicates via serial port, receive the message, RX led flashes. Onboard you can find the label: RX(receive ) When Arduino board communicates via serial port, send the message, TX led flashes. Onboard you can find the label: TX (transmit) USB to serial chip, can convert the USB signal into serial port signal. When the pin is HIGH value, the LED is on, when the pin is LOW, it's off. There is a built-in LED driven by digital pin 13.

the value used as the top of the input range).Īrduino board can be powered via USB connector.Īll you needed to do is connecting the USB port to PC using a USB cable. Used with analogReference().Ĭonfigures the reference voltage used for analog input (i.e. Reference voltage (0-5V) for analog inputs. Using pinMode(), digitalWrite(), and digitalRead() functions.

Or used as digital output pin to drive different modules like LED, relay, etc. These pins can be configured as digital input pin to read the logic value (0 or 1). Here is an explanation of what every element and interface of the board does:Īrduino MEGA has 54 digital input/output pins (of which 15 can be used as PWM outputs). Flash Memory: 256 KB of which 8 KB used by bootloader.To facilitate wiring, a 0.5 m USB wire is provided for you. We can power on by USB wire, DC head and Vin GND pins. This chip is burnt the firmware well before leaving the factory, therefore, we hardly use it. The built-in ICSP port can burn the firmware for ATMEGA2560-16AU directly. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, 1 ICSP header, and a reset button. Keyestudio Mega 2560 R3 is a microcontroller board based on the ATMEGA2560-16AU, fully compatible with ARDUINO MEGA 2560 R3.

6.3 How to Install the Driver of CP2102.See also the mapping Arduino Mega 2560 PIN diagram. Note that these pins are not in the same location as the TWI pins on the old Duemilanove or Diecimila Arduino boards. Support TWI communication using the Wire library. There is a built-in LED connected to digital pin 13. The SPI pins are also broken out on the ICSP header, which is physically compatible with the Arduino /Genuino Uno and the old Duemilanove and Diecimila Arduino boards. These pins support SPI communication using the SPI library. Provide 8-bit PWM output with the analogWrite() function. See the attachInterrupt() function for details. These pins can be configured to trigger an interrupt on a low level, a rising or falling edge, or a change in level. External Interrupts: 2 (interrupt 0), 3 (interrupt 1), 18 (interrupt 5), 19 (interrupt 4), 20 (interrupt 3), and 21 (interrupt 2).

Pins 0 and 1 are also connected to the corresponding pins of the ATmega16U2 USB-to-TTL Serial chip. Used to receive (RX) and transmit (TX) TTL serial data. In addition, some pins have specialized functions: A properly configured shield can read the IOREF pin voltage and select the appropriate power source or enable voltage translators on the outputs for working with the 5V or 3.3V. This pin on the board provides the voltage reference with which the microcontroller operates. A 3.3 volt supply generated by the on-board regulator. Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. The board can be supplied with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). This pin outputs a regulated 5V from the regulator on the board. You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin. The input voltage to the board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source).
