It probably wont work in a well lit room as a single LED wont change the resistance of the LDR
I´ve though about that, but that´s not a problem, since both arduino´s will be close

Good work! Better not let that resistor on the encoder board hit the USB socket or sparks might fly!

Hola amigo. Muy pero muy mal detallado tu problema. Muestra los planos del montaje para pasar de 24 v a 5 v. Muestra el sketch,  en fin, disculpa pero no somos adivinos y nuestro hechicero esta de vacaciones en las islas canarias.

Danos más información para tratar de ayudarte

See if it uses pins 0 and 1.
It doesn't, WIZnet shields use SPI.

Try this:
  • Remove the shield from the Arduino
  • File > Examples > 01.Basic > Blink
  • Sketch > Upload - After the upload you should see the LED on the Arduino blinking, on for one second, off for one second.
  • Unplug the Arduino from the computer
  • Plug the shield into the Arduino
  • Plug the Arduino into the computer
  • Look between the Arduino and the shield to see if the LED is blinking.

Does the LED blink the same as before with the shield connected?

does i have to connect my ethernet shield to the internet before uploading the sketch or it is not necessary to do that first before uploading the sketch.
It shouldn't be necessary. I have multiple different Ethernet shields and I can upload to the Arduino with any of them.

The display is not attached to any circuit board, yes I have the display with ribbon connections like it is shown here:

There are 14 pins. I have no clue about the signal names.

The display shows that pattern when it is first powered up and has not been configured by the library using the control and data lines.

The good news is the you have the display powered correctly and the backlight working.  There will be 6 more connections to data pins that you need to get exactly right as shown in this example here. Some pins will not be suitable for this (pins 0 and 1 on an UNO as they are used for the serial port).

You also need to setup the right pins in the sketch, see example here, otherwise the display will not get configured. It is critical that the pin order is correct.

Check solder joints are OK, no shorts between pins and nice clean wetted joints.

It looks like you are trying to use a single resistor, not a pot. as in diagram above to set the contrast. You should use a pot, but that is your next problem when you have the interface working.

i need to say it never work this shit arduino gprs module  based on M10

i never have success to maintain gprs connection more than one time

shhhhhhhhhhhhhhhhhhhhhhhiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiitttttttttttttttttttttttttt .
You already have the answer. You need to develop a way to anticipate the movement to the location where you want the weight and reverse the air to slow and stop the weight. Can you do that with the joystick? I don't know. The problems are three: compressiblity of the gas, temperature of the gas and the inertia of the weight. I guess there is a fourth, the distance to move the weight. Perhaps a 5th, the direction to move the weight.

Quite a list.

This thread is really nothing to do with the announcement thread about the library. I have split it off into a new thread.
