@Sparkman Thanks for the suggestion. I tested some other example codes and it didn't work either. I found out that the Wiznet 5200 I bought from radioshock does not work with the default Ethernet.h. I had to download Seeedstudios example library and modify their EthernetV2.cpp because it was broken out of the box. I found my solution for the .cpp from reddit and their example code worked afterwards. Then i just replaced Ethernet.h with EthernetV2_0.h and everything ran. As a side note i reinstalled the arduino ide and deleted my Arduino folder and started from scratch so I had reenable soft spi and change the pin 14,15,16 to A0,A1,A2 like suggested in the Disqus comments and now everything works.

EthernetV2.cpp code after mod:

#include "w5200.h"
#include "EthernetV2_0.h"
#include "DhcpV2_0.h"

// XXX: don't make assumptions about the value of MAX_SOCK_NUM.
uint8_t EthernetClass::_state[MAX_SOCK_NUM] = {

Is there anyway i can debug this or add something to the code to enable dhcp. How much space does enabling dhcp take up.

Thank you. I will try this and report back.

I built a ethernet gateway using an arduino uno and a wiznet 5200. In the serial monitor i get 0;0;3;0;14;Gateway startup complete. But i can't ping it or connect with the veralite. I've attached my sketch below. Where am i going wrong here:

 * version 2 as published by the Free Software Foundation.
 * 
 * DESCRIPTION
 * The EthernetGateway sends data received from sensors to the ethernet link. 
 * The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
 *
 * The GW code is designed for Arduino 328p / 16MHz.  ATmega168 does not have enough memory to run this program.
 * 
 *
 * COMPILING WIZNET (W5100) ETHERNET MODULE
 * > Edit RF24_config.h in (libraries\MySensors\utility) to enable softspi (remove // before "#define SOFTSPI").
 *
 * COMPILING ENC28J60 ETHERNET MODULE
 * > Use Arduino IDE 1.5.7 (or later) 
 * > Disable DEBUG in Sensor.h before compiling this sketch. Othervise the sketch will probably not fit in program space when downloading. 
 * > Remove Ethernet.h include below and include UIPEthernet.h 
 * > Remove DigitalIO include 
 * Note that I had to disable UDP and DHCP support in uipethernet-conf.h to reduce space. (which means you have to choose a static IP for that module)
 *
 * VERA CONFIGURATION:
 * Enter "ip-number:port" in the ip-field of the Arduino GW device. This will temporarily override any serial configuration for the Vera plugin. 
 * E.g. If you want to use the defualt values in this sketch enter: 192.168.178.66:5003
 *
 * LED purposes:
 * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
 * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
 * - ERR (red) - fast blink on error during transmission error or recieve crc error  
 * 
 * See http://www.mysensors.org/build/ethernet_gateway for wiring instructions.

I've been looking everywhere for this answer but I can't find it. Can you charge batttery powered arduino and run it using AC power. Pretty much i watch to keep my lithuim battery charged while power is connected to my arduino. Is this possible. It sounds like people have done this with solar but this device will not be outside.

This is my first project and I've learned a lot. I plan on improving the switch as I learn to design boards because I could have saved a ton of space if I could have build my own relay with built in 5v output from the load wire. But I'm happy with it so far.

parts list

• arduino nano
• NRF24L01
• Protoboard
• Surface Mount Box Extender HW187-52
• two radioshack pushbutton switches
• dual load relay
• in-sure Push-in Wire Connectors

Sorry for the bad pictures.

3 to 5 here

Same here. I'm probably going to just order a wiznet since that seems to be consistently working for most.

I'm extremely new to arduino and i've successfully got two devices running, for example a gateway and two button relay. I've gotten a 2.8' tft in and want to connect it to but I'm lost. If i connect everything pin of this to my nano I wont have any left to connect anything else. I bought a bunch of nano and dont want to go buy a full size arduino but will if i have to. Please help me figure out the best way to wire my nano to the tft/sd card shield.
