Pressure Logger

Projects General Guidance

Hi there.
Very new to this, need some help please.

Got a Arduino Uno board.
A SD card Shiled.
I use my powerbank to power up the Arduino board and shield and a separate power supply for the transducer.
I need connect a pressure transducer to it and log the data that comes for it onto the SD card and possibly graph it on a Adafruit 2.2 inch 18bit TFT screen (still need to get).
The pressure transducer needs a supply of 10-30 VDC, output of 4-20mA and a range of 0-16 Bar.
I know I need a 250 Ohm resister to convert the 4-20mA signal to a Voltage again which the board can then read.

Please assist in suggesting how I should go about wiring this all up as it confusing me extremely and also the coding side of things.

Thanks in advance for the help.

We strongly recommend to start with the simple examples that come with the Arduino IDE: learn the programming language, blink an LED, read the analog inputs, SD card datalogger etc. before starting on projects like this.
