File Write Example

# This  EZ-Script will log the positions of 
# servos D3 and D4 in the specified file. 
# The loop will repeat 10 times for 10 seconds

$filename = "c:\temp\myfile.txt"


$cnt = 0
$max = 10


  print("Writing line $cnt or $max")

  FileWrite($filename, "Time: $time")
  FileWrite($filename, ", Left Servo: GetServo(d3)")
  FileWriteLine($filename, ", Right Servo: GetServo(d4)")

  $cnt = $cnt + 1

  if ($cnt = $max)



File Read Example

$filename = "c:\temp\myfile.txt"

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



  $txt = FileReadLine($filename)

  print("Read: $txt")

  if (FileReadEnd($filename) = true)
    print("End Of File")


File Read with Splitting Fields By Coma Seperator Using SPLIT() Function

# Reads a file and seperates each field by a comma.
# The Split() function will return a
# specified field index

$filename = "c:\temp\myfile.txt"

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


$cnt = 1


  $txt = FileReadLine($filename)

  $DateField = Split($txt, ",", 0)
  $LeftArmField = Split($txt, ",", 1)
  $RightArmField = Split($txt, ",", 2)

  print("Row: $cnt")
  print("Date: $DateField")
  print("Left Arm: $LeftArmField")
  print("Right Arm: $RightArmField")

  if (FileReadEnd($filename) = true)
    print("End Of File")

  $cnt = $cnt + 1

SPLIT() Example #1

$x="one, two, three"

$first=split($x, ",", 0)
$second=split($x, ",", 1)

print("First Field is: $first")
print("Second Field is: $second")

SPLIT() Example #2

$x="one - two - three"

$first=split($x, "-", 0)
$second=split($x, "-", 1)

print("First Field is: $first")
print("Second Field is: $second")

Upgrade to ARC Pro

ARC Pro is your passport to a world of endless possibilities in robot programming, waiting for you to explore.


D.J. You are Truely Amazing! and part Magician , I think.



awesome DJ great work,looking forward to the next the speech recognition add-on


FRED tells me to DOWNLOAD immediatly......Thank you so much "robotinDJskies" very appeciative ,Glen(FRED'S master) :)


Sweet! ARC, the gift that keeps on giving!


Thanks again DJ! Again wish I was not stuck in a hotel room and could be building and testing! Soon.


DJ looking at you file read command looks very good,i did have a question about adding my own jokes using text file ,but this will work,i know you can look up jokes on the internet with a script ,but not the same thing,good to put different jokes on a text file and random read them GREAT JOB DJ


@Robotmaker...DJ has an example of script for random speech using varibles called nouns, verbs and adjectives and randomly mixes themup EXAMPLE 23!...sometimes they ARE very could do the same for you joke idea.. :)


yes i saw that before,i had plans to use it i see this board EZB needs a lot and a lot of programming in scripts

United Kingdom

It doesn't NEED it, but it makes it better. Luckily writing the scripts is easy (or EZ) :)


RobotMaker, you won't be asking as many questions once you start using it :)

To give you an idea, there are many thousand users of the EZB, and we only have a few ppl who ask questions on the forum :). The rest just use it, or learn from watching some of these questions. Everything you have ever asked is possible and easy within ARC, but you'll need to actually use it first lol :)

That is the reason our forum rules strictly limit posts to helpful EZ-Robot building information. We receive thousands of unique visitors viewing the forum daily, and they are mostly existing users. The forum is a knowledge of community support to help others and define new feature suggestions. There are many thousand existing forums online that will provide you're daily dose of drama - just not here:) we're building robots and changing the world!
