Paul thanks for the tip, I'm a newbie and I'm still learning!!

Here is the code attached, can't find what I'm doing wrong.

2  Using Arduino / Project Guidance / UNO + ETHERNET SHIELD and SD + LCD KEYPAD on: January 16, 2014, 06:23:16 pm
Hello there!
I'm having some trouble with my project, I have tried everything but now I'm stuck!!

I'm trying to build a temperature logger, so far I have managed to work it out:
- Solved a pin conflict between lcd shield and ethernet + sd shield
- Can write in SD (while not using ethernet) and built a server to access registered files (while SD is disabled)
- Print temperature in LCD (1st line)

Everything worked fine until I tried to write in the LCDs 2nd line, lcd.setCursor(0,1), I can't access SD card and save temperature data anymore. Strange things start to happen, if i change the text showed in the LCD, I can't save... By the way, to get the cursor to the 1st spot in the 2nd line I have to use lcd.setCursor(-4,1)...

Any idea? Anyone has come across a similar problem?
I'll post the code as soon as I clean it up a little

Hi there!

It looks that your configuration is very similar to a project I'm developing, with no success so far.
I have a problem with a conflicting pin (number 4), which appears you have solved. I have managed to follow the conversation thread using Google translator but I get lost when watching the video (the close captions makes no sense), so I have a few questions:
First of all, you change pin 4 → pin 3 in the skectch, and then have a device (jumper??) soldered in pins 1 and 2, why is that so? Can you give me more details on that configuration?
Then, when connecting the Ethernet shield you bend pins 4, 10, 11 12, 13, again, could you explain why are you doing that?

Thank you in advance!!!

Muchas gracias por la información!!

Allá vamos!

Me gustaría empezar a trastear con el Arduino, pero hay tanta variedad e información que estoy totalmente perdido. Como novato total estaba pensando en comprar un kit con un poco de todo. De proyecto a medio plazo me gustaría construir un data logger de temperatura. ¿Me recomendáis algún kit en particular? ¿Alguno que venga ya con los componentes necesarios para el data logger?

Y ya puestos, para empezar, ¿alguna página o tutorial en concreto para empezar de cero?


Para que veáis mi nivel de novato, ¿es lo mismo un Arduino que una Rasberry PI? smiley
