arduino control board sketche connected to load cell

Load Cell signals:

50 Kg capacity load cell will monitor maximum load 300 N, or max 30.6Kg.f

It is 4 wire load cell will run on “Arduino uno” through “HX711 shield “ .

Needed sketch details write code clarifying pins connections on Arduino uno :

1- Interfacing mentioned load cell with 2mv/V output with Arduino through HX711 taking readings with highest possible rate “ex: every 1 millisecond ,or less ” >> displaying reading on LCD screen in N ,or KG.f with [url removed, login to view] resolution ,or 0.01 if possible. With filtered readings without noise.

2- With updated fast reading >>digital output signals according to value of reading as follows :

a) Reading increased from zero to just [url removed, login to view] ( adjustable) >> activates digital output1 (touching signal).

b) Exceeding limit of load cell designed capacity (330 N) ( adjustable) >>> activates (overload) digital output2 and alarm message on screen “overload “.

c) Peak value of successive continuous readings >> will activate( peak value ) digital output3 and message of hardness =” the reading of local peak ,or maximum load value ;as example : 65.1 N detected from successive readings 0,1,2,…………..63.5,64.6,65.1,64.4,30,20,11,0 ” >>>>store this peak value in memory as sample reading of hardness >>> display sample reading on LCD screen “hardness = 65.1 N “ .

3- Two Digital signals will be given {Digital input1 “ single “,and Dig-input2 “ Automatic batch “} :

a) Single sample mode will be displayed on screen and just having peak value it is ready on screen and ready to be printed.

b) Automatic batch mode will be displayed on screen and will ask user about Number of samples N ,and 12 digit Batch Number entries? And internal counter will count till reaching end of batch at N samples storing all samples values on memory preparing it for printing and statistics( avoid power failure data losses when you store results).

4- Printing samples readings ,or peak values on normal printer ,or thermal ( clarify printer type and connection please ) including :

a) its readings basic statistics { average ,min, maximum, standard deviation }

b) Enter and Print Date and Time to the report.

c) Enter a 12 digit Batch Number label appears on display and in printed report.

d) Calibration report at three points 5, 10, and 15 Kg.f.

e) Print-out of force increase curve vs time for samples.

f) Display: LCD Display for No. of samples, and hardness, or peak value results.

g) Keyboard: Numerical and function keys.

h) Number of tests prior to statistic: Up to 250.

5- Calibration menu for the hardness test station at any desired point as piece-wise linear method.

6- LCD display and optical keypad board Interface.
