(8) Reset button  resets both the W5100 and main Arduino / Freeduino motherboard. Each of the 54 digital pins on the Arduino 2560 Mega can be used as an input or output, using pinMode (), digitalWrite (), and digitalRead () functions. (7) LED indicators for Power, Link, Full Duplex, 100M connectivity, Tx/Rx, and Network Collisions. (5) Houses a standard RJ45 ethernet cable jack. (4) Supports 4 simultaneous socket connections. The module carries an onboard WIZnet W5100 Ethernet chip, which provides a network (IP) stack capable of both TCP and UDP, as well as a standard RJ45 Ethernet jack.įor more information here: Sample code, Ethernet library. Allows you to connect your Arduino UNO 328 or Mega 2650 1280 to a network or the internet AND retrieve or store files on a Micro SD Card. ARDUINO MEGA 2560 Pin 53 (SS) problem NDarwish April 19, 2016, 9:53am 1 hi, I'm using arduino mega 2560 for my project and there is only one SS (slave select) pin and I need 2 SS pins any way to do it without using another micro-controller I will be very grateful for any help. Just plug this module onto your Arduino board, connect it to your network with an RJ45 cable (not included) and follow a few simple instructions to start controlling your world through the internet. I have uploaded the 'ArduinoISP' sketch to the my Arduino Mega, connected the 10uf cap between reset and GND and Ive tried hundreds of times with the example 'Blinking LED' without success (Ive changed the pin13 that comes as default on the sketch by pin 4 of the Attiny13A). The Arduino Ethernet Shield connects your Arduino to the internet in mere minutes.
