help starting 7 inch touch screen project

Projects General Guidance
1

I am very new to arduino, i would like to know if my project is feasible.

i am trying to create a monitor for a small square baler to count, manage pressure and weigh bales- i have attached a picture of how i would like it to display on the screen and a description of the functions below;

FlakeCount - every time there is a rotation past a magnetic sensor or reed switch it counts +1

BaleCount - every time there is a magnetic sensor or reed switch triggered it counts +1 and resets the FlakeCount to 0

HydraulicPressure - display hydraulic pressure from a pressure sensor

AdjustPressure - on the touch screen have an increase button and a decrease button which controls a motor- everytime increase is pressed the motor spins clockwise momentarily, every time decrease is pressed the motor spins anti clockwise momentarily

BaleWeight - every time a switch is triggered it takes a weight and displays until the switch is triggered again, then the new weight is again displayed

BaleAverage - displays average weight from BaleWeight

if anyone would like to offer any help or feedback it would be greatly appreciated

Hi,
Welcome to the forum.

Can you tell us your electronics, programming, Arduino, hardware experience?

This is not a beginners project. You will have to consider the format of the input devices, such as your pressure sensor and the weighing station.

The project will have to be built rugged enough to withstand a farming environment.

limited programming skills of C++, zero arduino and hardware experience.

I had done a couple of subjects at University doing basic programming, but that was over 10 years ago now.....and i wasnt much good at it then

I have ordered an analogue pressure sensor found here - http://www.ebay.com.au/itm/122342383073
and a 7" screen found here- https://www.jaycar.com.au/7-lcd-lvds-touch-screen-monitor-to-suit-xc-4350-pcduino/p/XC4356

I am yet to order a load cell for the weighing station or any modules/boards

the screen will be mounted in an enclosed tractor cab with wiring running out for all the inputs.

I have been considering outsourcing a programmer to write the code if this is going to be too difficult for me

thanks for your reply!

finding load cells with 4-20ma output is common and they make
arduino shields that read that output, because most arduino shields
come with example codes, is should be a fun project.
