The Mega 2560 board is compatible with most shields designed for the Uno and the former boards Duemilanove or Diecimila.

and this is the code i use for testing: include PIN 50 is connected to Uno’s PIN 12, Mega’s PIN 52 is connected to PIN 13, and Mega’s PIN 51 is connected into Uno’s PIN 11. You will lose or gain a couple of second (might even be minutes) a day on your time. In both boards we connect the GNDs to achieve common ground, and also Pin 10’s together.

So you get completely separate pins for each SPI device. Tx, Rx) and also another adjacent pin for the clock (eg.

But yes, TimeLibrary can be used without RTC (Real Time Clock, of which the DS1307 is an example) but then it relies on the timing of the Arduino which is not very accurate. Specifications DC Current per I/O Pin, 20 mA Supported battery, 9V battery Power Supply Connector, Barrel Plug Clock speed Main Processor, ATmega2560 16. As for the pins, judging by the data sheet, including the pins diagram, if you set the USART into SPI mode then you use the 'serial' pins as SPI pins (ie.

It featuress 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, an ICSP header, and a reset button. The TimeLibrary is also not part of the Arduino just like DS1307RTC Library. The Mega 2560 R3 Board microcontroller is based on the ATmega2560.
