XTAL1,XTAL2: The crystal oscillator (16Mhz) is connected to the controller clock and is grounded through 2 bypass capacitors.ĪREF: Using this pin, when we use ADC for analog-to-digital conversion, use external reference voltage for conversion instead of reference voltage from internal 1.1V or 5v reference. Theyre numbered 54 (analog 0) through 69 (analog 16).

The Arduino Mega has a built-in reset circuit, a key reset system, and can be used as a reset controller for other devices. YES, you can use Arduino Mega analog-in pins as digital input and output. RESET: (Reset input) The low level of this pin exceeds 4 clock cycles and the board will reset.

The Arduino Mega 2560 also adds features such as analog comparators, external and software interrupts, power save mode, built-in temperature sensor, RTC, and more. USB (Programming with ATmega 8), ICSP (programming), SPI, I2C and USART Arduino Mega 2560 Hardware Specifications Arduino Mega 2560 So for some more complex projects, this is an excellent choice. ATmega2560 Microcontroller The heart of the Arduino Mega platform is an 8-bit AVR family microcontroller ATmega2560 with 16 MHz clock speed. The power source is selected automatically. The Arduino Mega 2560 is a replacement for the older model Arduino Mega, so, it will be named the '2560' extension. The Mega 2560 can be powered via the USB connection or with an external power supply.

Other features of the Arduino Mega 2560 include JTAG support for programming, debugging and troubleshooting large flash and SRAM that can easily handle bulky programs it is also compatible with different types of modules such as high-level (5V) or low-voltage Flat (3.3V) and I/O ref pins it supports ICSP and USB microcontroller programming on the PC side. There are more than 5 sets of Vcc and Gnd pins, which can easily connect other devices to the Arduino Mega 2560. Built-in RTC and other functions, such as analog comparator, advanced timer, controller wake-up mechanism interrupt, etc., 16MHz crystal clock can get 16 MIBS, and it saves power and is fast. For example: it has built-in 16 analog sensors and 54 digital sensor interfaces, and supports USART and other communication modes. Arduino Mega 2560 has many features that other boards do not have.

Why choose Arduino Mega? The main reason is that this board is more convenient for expansion.

Thanks for the info on using serial input as a command.There are cheaper Arduino boards on the market. Wow! 49 switches with only using 14 inputs! Fantastic but I looked at the library and it is above my level of expertise but I will work towards it. Incidentally some MEGA clones (I know of the Seeeduino one) bring out more pins to headers, the The typical input resistance of CMOS circuit at room temperature is in the 10^10 to 10^11 ohms range,Īt higher temperatures it can drop preciptously to 10^8 ohms or so, in practice you've never notice. TheyĪre exactly the same as any other digital pin when used as digital pins. The analog pins are only connected to the ADC when a call to analogRead selects them anyway, so if youĭon't call analogRead on a pin, its isolated from the ADC (again by a practically infinite resistance). Shows the equivalent circuit and load capacitance which become important at higher frequencies. The ADC has a much higher impedance than that - it is precise to better than one part in 1024 with a 10kĭriving impedance, so clearly its impedance must be > 10M - at DC. The voltage regulator operates in a range of 6 to 9V DC. the ADC 30k impedance) - or if that only comes into play given an analogRead (vs. The board can be powered directly through the Micro USB connector or via the Vin pin. I'm not certain how well the 'analog in' pins work as digital inputs (viz. A power supply adapter that provides from 7 to 12V (Volts) of DC (Direct Current) is required. The input voltage to the Arduino board when its using an external power source (as opposed to 5 volts from the USB. All pins are capable of digital output, even the 'analog in' pins. Some Arduino boards like UNO, MEGA and DUE, come with an AC socket that can be used to power the boards and to supply additional voltage if needed.
