Code for 3 point bending device

[rosendobme2024]

Good day Arduino users. I have an application that requires me to utilize a load cell that is to operate a 3-point bending device for measurement of Elastic Modulus and Yield Strength of Calcium stones. We are revitalize an old 3-point bending device that previously used an old/out-dated PCB from 12 years ago. We have had to scrap the board and are trying to use the Arduino Uno R4 Wifi as the new operator for the device. My team and I are working on the code, which we need advice and direction on. Starter code that we are using is the Temperature sensor tutorial that came with the starter kit for Arduino beginner users.

Here are the images of the...

1. The Omega Load Cell
2. The BridgeSensor
3. The current Arduino setup for Temp reading
4. Connector from the sensor

The OMEGA bridgesensor is Model DMD-465

Below are the specs for the OMEGA LCEA series load cells.

SPECIFICATIONS:
Output: 0.5 mV/V #10% (end user must calibrate to eliminate 10%)
Excitation: 5 Vdc (8 Vdc max)
Non-Linearity: 0.5% FS
Hysteresis: 0.3% FS
Zero Balance: #1 mV/V
Bridge Resistance: 350 h
Construction: Aluminum with acrylic resin protective coating
Operating Temperature: -10 to 80°C (14 to 176°F)
Compensated Temperature: 0 to 65°C?(32 to 140°F)
Temp Effect:
Zero: ‡0.1% FS/°C
Span: ‡0.1% rdg/°C
Safe Overload: 200% FS
Lead Wire: 6" 30 AWG, pigtail leads

Wiring: Red= + Excitation, White= - Excitation, Green= + Output Signal, Blue= - Output Signal

What we need:

1. Arduino Code to operate the actuator for the sensor loading, retrieve signal data for outputting to excel in data table, output to LCD: Pressure and Elastic Modulus
2. What items do we still need to purchase to complete the setup. We know that Arduino boards are limited by 5V so are there other amps or devices we need?
3. Is there a better Arduino board for this application for final product after developing on a Arduino UNO R4 Wifi?
4. Are there other forums or resources that you recommend to reach out to for help?

application for final product

Are you trying to commercialize this? Not to be rude, but from the questions that you're asking, it may be wise to consult with someone experienced.

You should be able to use the Sparkfun HX711 load cell amplifier with that load cell. Consult their tutorial to learn how the load cell and amplifier work.

Interesting project but we are not a free code writing service. We will help out with your code but first you have to make an attempt to write it, post it and explain what is not working properly. If there is hardware it is always best to post links to technical information as there are many versions of the same or different items. Since we cannot see your project, my eyes are to weak, you need to post an annotated schematic (best) or a clear picture of a drawing. Pictures never hurt. Frizzing diagrams are not considered schematics here.
