Basic help

Postby Stroh » Wed Sep 09, 2015 6:05 pm

I am having trouble getting past the Software configuration section of the “simplified assembly process” (I didn’t think I was an idiot, but I could be mistaken). Apparently it is not simplified enough for me.
I have connected the DFRobot to my computer with the correct USB cord and the two relays click on and off and the leds blink. I have successfully installed the drivers for the DFRobot board (device Manager recognizes it).
I have downloaded the MyDoorOpener project software. It resides in My Documents directory and the files look like the ones in the example shown.
I have downloaded the correct Arduino IDE software for Windows. It resides in the C:\Program Files (x86)\Arduino folder.
I am double-clicking the MyDoorOpener.ino file (in the My Documents directory) to edit the IP address and password. I don’t see how to determine which is line ~53 for the IP address, or –line ~58 for the Password change. Is the IP address change I need to make in the following lines somewhere?
#include <Time.h>
#include "MyDoorServer.h"
// Global configuration (adjust to reflect your setup)
// EthernetShield IP address (DHCP reserved, never allocated to anyone else). This is the internal
// network IP address you want your Arduino assigned. This is not the address you will be accessing
// your Arduino from the iPhone application or internet ... You need to configure NAT forwarding
// on your home router to do that. See for more details.
uint8_t ip[4] = { 192, 168, 0, 13 };
// Port on which Arduino HTTP server will listen to
int port = 80;
// MAC address to be used by ethernet adapter
uint8_t mac[6] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };

Is the following (in bold) where I need to replace “xxx” with my password?
(// password required for operating door [max length = 16] (status fetching doesn't require password). This
// must match the password you set in the iPhone application (be careful as case is sensitive).
char* password = "xxx";

I have tried to upload the MyDoorOpener program (Sketch) to the board (without changing password and IP address) but I can’t figure out how that is supposed to go either.

When you're in the Arduino IDE, look at the bottom left of the program, in the status bar. You'll see the current line
number at which your cursor is located. As you move the cursor up and down thru the different lines, that number will
go up and down. That will help you identify which line is which ... ;)

Basically, the IP address line is:
Code: Select all
uint8_t ip[4] = { 192, 168, 0, 13 };

and the password line is:
Code: Select all
char* password = "xxx";

Change those values to match your specific setup, for example based on your network IP address range as well as the
password you'd like to use to communicate between the iPhone app and the Arduino micro-controller.

Hope this helps,
