7 Led Segment

Asked Nov 2012 — Edited Nov 2012

I am trying to control a seven led segment with ez-b but I not sure how to go about it. Do I have to use 7 different connectors from the ez-b like I would do with an Arduino board?

I is the same type of 3 pin connectors like you use on the arduino. There is ground and hot and signal. But, with the EZB it is WAY MORE Easier.

It depends on that hardware you are connecting. If it's 7 seperate LED's without a shift register IC, then yes you'd need 7 ports of the EZ-B. Each port would represent a different LED.

In ARC, you can create a function that will display the single digit of a variable by monitoring the variable value. If you need help we can create an example.

An example will be great DJ, so I can get familiar with the EZ-B

Use this example: Example-Script-7SegmentLEDDisplay.EZB

Quote:

Displays the value of $lDisplay on a 7 segment led display.

The Display Value EZ-Script Control loops and displays the value every second from the $lDisplay variable.

You can either use the Random script, or the speech recognition and verbally specify values to be displayed.

Instructions
------------
1) Connect to Ez-B

2) Press START on Display Value script

3) Press START on Random to display random number

4) Say one of many speech recognition commands (i.e. Set Value three)

Main procedure to display the value of $lDisplay is...

Code:

# Init
$lDisplay = 0

:Start

  if ($lDisplay = 0)
    goto(zero)

  if ($lDisplay = 1)
    goto(one)
  
  if ($lDisplay = 2)
    goto(two)
  
  if ($lDisplay = 3)
    goto(three)
  
  if ($lDisplay = 4)
    goto(four)
  
  if ($lDisplay = 5)
    goto(five)
  
  if ($lDisplay = 6)
    goto(six)
  
  if ($lDisplay = 7)
    goto(seven)
  
  if ($lDisplay = 8)
    goto(eight)
  
  if ($lDisplay = 9)
    goto(nine)
  
  if ($lDisplay = 10)
    goto(ten)
  
  if ($lDisplay = 11)
    goto(eleven)
  
  if ($lDisplay = 12)
    goto(twelve)
  
  if ($lDisplay = 13)
    goto(thirteen)
  
  if ($lDisplay = 14)
    goto(fourteen)

  if ($lDisplay = 15)
    goto(fifteen)

  Sleep(1000)

goto(Start)
