lcd keypad shield - really no useful schematic?
df0021 2012-05-28 17:18:30 5697 Views6 Replies Hello
I try to connect sensors to the lcd keypad shield, but I can't find out, where the free I/0 ports are.
I did find only poor plans of the shield. May be are the digital ports in j5, but on the shield is j5 not marked.
Google shows more than 9000 hits, but oftens with the well known bad plans.
It would be very nice, if somebody of the experts could explain to me, where I can connect the sensors.
regards

2012-06-08 12:56:30 Hi kingkobe,
please excuse my late answer. I didn't check the forum.
I have no connection to the analog ports at all. What you see is the plus and minus lines for my digital device I have used.
I use the Arduino in order to measure the temperature by SMT160 30. It is connected to plus/minus (what you can see) and a signal line to a digital port.
It works well, but my problem is to bring the values in form of a curve to a screen. I'm afraid this will be a hard work (I did not yet start).
If you want to acces to the analog port, you have to write analogRead(pinnumber). I wondered about the number 0, 1, 2... like the digital ports with the same pins 0, 1, 2,..... The difference is analogRead vs digitalRead.

Hi Hector, Ricky
it seems to be the latest version because I did it buy only a few weeks ago. On the board is to read "......V1.0".
I try to add a photo.

Hello df0021, I just bought one of these shields and I am trying to access the analog ports. What is the name of the part that you have connected at the bottom right of your picture?
Thanks! kingkobe

Have you seen the schematic? It is clear which pins are used for the LCD and buttons.
The LCD is using digital pins 4-9
The Buttons are all on 1 analog pin: A0
That means the rest of the pins are free for use. You can also see in this picture.

have you seen this website? [url=http://www.shieldlist.org/dfrobot/lcd]http://www.shieldlist.org/dfrobot/lcd[/url]
Shieldlist.org provides lots of information about many boards including many of our DFRobot boards. Could you post a picture of the LCD shield you are using, we have 2 versions. I will provide the best info for the Shield you have.
