How Many Lines Can Be Added To An EZ-Script

i have a design that works perfect but uses arduino board (i know you care for it )
but here is the problem been looking to slove for a long time
its a SPECTROMETER i guess you know what it is
now it uses 7 leds of differnet color of the spectrum including IR AND UV and photo dide to ADC input that look easy
now hard part the code from arduino BOARD TO YOURS
very long code because each led has a value plus a code to go with it times 7
for each sample of liquid,plus other codes then start up code and automatic code righter when you push a button for sample under test it rights the code
and serial code to lcd

can it be done with your great board and have any ideas,great sensor for robotics on liquids,i want it mostly to tell different bar drinks apart and BEER


Upgrade to ARC Pro

ARC Early Access will give you immediate updates and new features needed to unleash your robot's potential!

There is no limit to the code size, really. I mean, there probably is a limit but you're not going to reach it.

I'm certain everyone on this forum is excited to see you build a robot. I would recommend building an EZ-Robot first. Load ARC and follow the Tutorials and build an EZ-Robot to understand how ARC works. Once you have built your first robot, you will be familiar with the controls and how to build your next robot or expand onto it. You can also begin adding your advanced features with EZ-Script. You may find that EZ-Script fulfills your needs... If not, then switch to C# or VB .Net:)

Your requirements can be done easily once you start building a robot. Your requirements have nothing to do with the board itself. The EZ-SDK was designed for advanced custom robots. To begin with programming, I would begin by taking a course in C# or VB .Net to learn the basics of programming in those environments.

The EZ-BoxBox can be found in the tutorial section, and is a great starter project. It will help you learn how to build an EZ-Robot. Building the BoxBox will help you understand the process to building a robot.

There is a process to building a robot, I would recommend following the Tutorial section to build a robot. Once you have a robot, you can then begin adding features like this request.
you dont need to build a robot to work on the codes,some days i try the board and examples to get use to it ,and some days i work on the robots as parts come in
i give you these ideas for add-ons now so maybe 3 months or 6 months or a year it may be out
you have so many people asking you for add-ons
writing the code on the arduino not done by me,so i dont know how to use it on EZB
my omnibot should be finish fairly soon,i do have another in site 90% done IROBOT ROOMBA project it has it mostly wired up with ezb mounted
only stop because of my main project my omnibot 2000 design first.just like others like my friend JOSH i think he has 3 started too not finished
will try the boxbox idea wednesday night

update i look at the boxbot idea ,way too easy for me
i just use the board only hook a few servos and try the code,and same with sensors too ,on my bench,that best way to get use to the ARC
and using the examples,i call it a breadboard idea
One of the things I would recommend is modifying the code to read from a text file. That way you can obtain the liquid type form a text file.

I suspect the sensor reads ADC? If so, create a comma separated text file in Excel with the ADC range of each liquid. Then you only need to do something like this...

In your CSV:
1) the first column is the minimum ADC value for the liquid
2) the second column is the maximum ADC value for the liquid
3) the third column is the name of the liquid

Here is an example CSV...
10, 15, Beer
20, 28, Water
30, 45, Oil
66, 80, Hair Gel
90, 95, Banana
120, 160, DJ
170, 185, Milk
190, 210, Vanilla Ice Cream Yummmmmm

Here is the EZ-Script code...


$filename = "c:\robot\liquids.csv"

if (FileExists($filename) = false)
print("$filename does not exist!")

# Get the value from the sensor
$value = GetADC(adc0)


# Loop through the file to find the matching value

# Read the line of text from the file
$line = ReadLine($filename)

# Split the line of text into fields and use a COMMA as the separator
# Because the file was created in Excel as a CSV
$fieldMin = split($line, ",", 0)
$fieldMax = split($line, ",", 1)
$fieldName = split($line, ",", 2)

# Check if the ADC value is within the range of the field
if ($value > $fieldMin and $value < $fieldMax)
print("Match found!")
print("Detected liquid is: $fieldName")

# Reached the end of the file, must not be a match
if (FileReadEnd($filename))
print("Did not find match")


Voila! That's an incredibly simple and elegant solution. Way better than the Arduino code:)
how does the automatic function work
hard to get all those values
and there is 7 of them too so how do you add 7 values from one ADC
very funny DJ 120,160

DONT have or never use EXCEL
i guess wordpad or notepad be ok and change csv to txt

how does the automatic function work

very funny DJ 120,160

WILL find the code and post a example of the code
// variable declaration
int inPinRed = 3; // red button on pin 3
int inPinBlack = 2; // black button on pin 2
int redState; // is red button pressed
int blackState; // is black button pressed
int val = 0;
int analogPin = 1; // sensor output connected to Analog Pin 1
int sensorValue = 0; // variable to store the ADC value of the photodiode
int red = 6; // red led on output pin 6
int yellow = 7; // yellow led on output pin 7
int ir = 8; // IR led on output pin 8
int blue = 9; // blue led on output pin 9
int orange = 10; // orange led on output pin 10
int pinArray[] = {6, 7, 8, 9, 10}; // pin address array
int count = 0; // for next loop counter
int sampleValue[5]; // sample value array
int windex[] = {38,1019,564,321,315}; // database values for windex
int windexValue; // windex value
int windexTemp = 0; // windex value - sensor value for ID
int motoroil[] = {31,1020,787,283,193};
int motoroilValue;
int motoroilTemp = 0;
int coffee[] = {38,993,41,351,286};
int coffeeValue;
int coffeeTemp = 0;
int softsoap[] = {31,1020,708,379,58};
int softsoapValue;
int softsoapTemp = 0;
int water[] = {33,1017,582,327,45};

here is part of it
That's terribly written code. Absolutely terrible!

However, I do see that there are 5 values per reading. So you will need to modify the code to split by more fields. And it doesn't look like a range, so simply use the EQUAL sign instead within the IF condition.

Ugh, that code hurts my eyes :(. Creating separate variable arrays for each "liquid" is an example of very bad programming. The example I demonstrated to you in my above post will read from a file to find the appropriate matching liquid - and only be a few lines of code... Rather than a billion lines of IF conditions like I imagine that one to be.

You can even create a learn feature to write new lines to your CSV. So you can teach your robot new liquids.
it was done by a guy who sell real good spectrometers from his business some over $1000,but they are pro versions and not using arduino board,made it for others using arduino boards
just something simple for others using the arduino board
automatic code add in code near bottom i think,you put a sample press i think red button and code values are entered,on lcd you do need to name it
code is only pages on txt file i know
so how would you use the learn function
here is the learn function
learn: // learn subroutine
Serial.print(" Learn Mode ");
for (count=0;count<5;count++) {
digitalWrite(pinArray[count], HIGH); //turn the led on
delay(100); // wait for stabilization
sensorValue = analogRead(analogPin); // read the value from the sensor
if (sensorValue <= 99) // test for number of digits to display
{Serial.print(32, BYTE); // insert space
if (sensorValue <= 9) // test for number of digits to display
{Serial.print(32, BYTE); // insert space
Serial.print(sensorValue),Serial.print("-"); //send as a ascii encoded number
if (count == 0)
{Serial.print("Red ");

as you can see half the code is for LCD
I really enjoyed this thread. I'm sure many people have learned something from it.


;) code
Yes DJ did a very very good job on the code like always
looking soon to post the very easy circuit,made some changes in the design ,like making the leds put out more output added more color spectrum,i added IR AND UV to get better accuracy and range
plus got in SMT leds and photodiode to make it much much smaller.

But it will take some time,i have my omnibot 2000 to finish first,but my gecko cage project might need faster,since FEB 14 HAVING THEM MATED and few months latter baboies ,yes yes yes,ggoing to be another daddy soon,since they need help to hatch,feb 14 a very big day for me and my girlfriend
since she holding the lady netri and i have jake

DJ what do you meen by EQUAL sign with the IF
I dont know what each one meens or how to use it,have any info on it
