as you can see in the subject im searching help at least for my “little” project.
to understand what im trying to do:
i want a small processing unit with a lcd what acting like a terminal.
the sensor has acually a 4-20mAh output, is it possible to work directly on arduino with this output?
if not, there is a sensor available with 0-4,5V output ← this should go with the digital input from the arduino.
i want a touch lcd on it where i can programm a menu with buttons.
on a button click the ardunio should record the values from the sensor to a sd card.
after collecting some records it should be possible to send the data via bluetooth or wifi? to a pc?!
can someone say if this is possible and what i need for this?
i found for exsample http://www.adafruit.com/products/330 this lcd, whould it be possible to add bluetooth and a option for reading a sensor?
hope you can help me an sorry for my ultra bad english
