Unfortunately I did not get any response on the LCD screen.
I do not know how to connect the LCD to the Arduino smiley-sad

It is manufactured by Freeborn Electronics Co, Ltd. Shenzhen http://detail.net114.com/chanpin/1003690432.html
I requested data sheet - I hope I was understandable smiley
The price of this LCD is 2.5 USD

Hello!
I have an 8-pin LCD  jrm-6877
5V, GND, DATA, CLK, CS, LED, GND, PB
How to connect the LCD Display with Arduino UNO?
Can you make me a diagram?
There is a library to be installed?

Nice project !
How to edit the schetch to use ethernet shield based on wiznet5100 an DHT22 tmperature sensor  ?

I use the 500A 24V lead acid batteries. Want to attach an ethernet shield my project to monitor temperature and battery voltage.

I created my automation wiring pcb
It would be interesting to be able to add an ethernet shield to monitor online  charge cycle and voltage from the batteries smiley
ICSP connection between Arduino and Ethernet shield is necessary?

wow! brilliant smiley
 thank you very much smiley

I have a battery charger 24V 50A
Help me build automation using Arduino and relay?
I want the Arduino to monitor battery charging as follows:
When the battery voltage reaches 29V arduino  engage a relay  and disengage the relay only when the battery voltage drops to 23.5 V.

I get this error when verifying code
https://dl.dropboxusercontent.com/u/167251214/Poze/eror.jpg
If remove (case '10 ': case '11': case '12 ': case '13': case '14 ': case '15' ) code only works for the first 10 relays.
The other five commands  appear in the table but does not work properly
10  Using Arduino / Programming Questions / Re: Arduino Mega 32 Relays Web Server on: May 30, 2013, 12:22:04 pm
This is the code modified by me for 15 relays. https://dl.dropboxusercontent.com/u/167251214/iphone_ethernet_sw_mega/iphone_15_relays.ino
Work properly only the first 10.
Where I'm wrong? smiley-sad

Hello!
Use this code https://dl.dropboxusercontent.com/u/167251214/iphone_ethernet_sw_mega/iphone_ethernet_sw_mega.ino to control 10 relays via the internet and works well on the arduino mega.
Help me modify the code to order all outputs on the arduino mega?
I tried to do that and I was able to add controls to the web page but the code does not work.
Please help.

12  Using Arduino / Microcontrollers / Re: Arduino ISP help on: April 27, 2013, 09:08:41 am
After writing a code.hex the ATtiny 2313 can not be erase - it gives me this error:
Code can contain the write protection?
We can fix the chip in this case?
This is the code I was talking about:https://dl.dropboxusercontent.com/u/59457677/code.hex
It can remove write protection with notepad?
13  Using Arduino / Microcontrollers / Re: Arduino ISP help on: April 27, 2013, 07:17:01 am
We succeeded! smiley
I tell you how I did it.
1. I created a Windows Batch File with the following instructions:
2. I put the batch file (in my case main.bat) and main.hex in the same folder.
3. We connected Arduino ISP programmer mounted on COM3.
4. We executed main.bat and ready

How to erase the chip now ?
14  Using Arduino / Microcontrollers / Re: Arduino ISP help on: April 25, 2013, 02:39:14 pm
I used these settings for the avrdude-GUI and when I press the Write or Erase-Write-Verify gives me this error
I wrong somewhere?  smiley-sad
15  Using Arduino / Microcontrollers / Re: Arduino ISP help on: April 25, 2013, 09:40:36 am
I installed WinAVR ... after restart I put in C :/ Windows folder code.hex file.
I connected the Arduino to the computer on COM3 - I installed Arduino1.0.3 and I uploaded ArduinoISP from Examples.
I disconnected the Arduino from the computer and I installed AVR Programmer bought on Ebay .
I uploaded blink of examples / basics and works - LED conected on pin 7  blinks
Then I typed Run - cmd - avrdude-p-c ATTiny2313 stk500v1-P COM3-b19200-Uflash: w: code.hex: ENTER and I got the error in the picture attached here
Please help me with a step by step tutorial smiley-sad
