Limiting Resistor Calculator
-- Page: 1
This is just a simple LED limiting resistor calculator
I wrote in VB. It helps you determine the resistor value you need for
your mod LED projects. It can show the actual calculated resistor
value and the nearest higher standard resistor value. The standard
resistor values are based on the listing in the Digikey catalog.
So far, it only has the LED limiting resistor
calculator, a little resistor color code utility, and a 4N25
optoisolator Multi-LED resistor calculator. I will be revising this to
make the optoisolator value be user definable. Use the same V and mA
values on the Limiting Resistor calculator and indicate the number of
LEDs to be used in the optoisolator.
Download the LEDcalc here. I'll update this when I do
some changes, bug fixes or extra features.

This file has been downloaded 6102
The zip file contains the Setup files for the LEDcalc.
Just run Setup.exe and install it like any other program. This
includes the VB runtime files used. I will prepare a pack without the
runtime files to keep the pack at a small size since some of us
already have the runtime files installed.
- v1.5.5 - Removed some embarrassing programming errors, and added
a weblink to the GT logo graphic (thanks to Thom Humphries)
- v1.5.4 - Fixed Daneel's 5-band resistor function error, where
values displayed from the calculation does not reflect on the
resistor coloring and value.
- v1.5.1 - Added 5-band resistor function - thanks to Daneel :)
If you experience any bugs, errors or just want to
give a suggestion, complaint or why I should stop doing such things,
an e-mail :).
