i want to design a electric roulette wheel. it will not have a big metal ball. it will not turn. it will have lcd lights. 37 lcd lights. each lcd light will be turned on by a transistor. each transistor will be a bc107. each transistor base will be connected to a pin of a processor. i can use microsoft excel or word or adobe pdf to make it random. but noone of these couldn't fulfil my requirements.
my dear friends, can u suggest me a appropriate application for this job.
i will patent the idea. do not copy it/
Why do you think you can just look for an already existing application?
With the exception of the random number generator, the code for this would be very simple. How about actually _you_ write the code?
Another thing - 37 diodes? I would go for a shift register solution and (depending on amount of current needed for the LED:s) buffer chips instead of the transistors.
If only few LED are lit, then many processors can manage the LED:s directly without any external components except series resistors as current limiters. Many processors would require that the LED is connected to VCC and the processor sinks the current to GND since many processors are more capable at sinking current than at sourcing current.
Obviously, few processors would be able to stand the full load of all 37 LED lit at the same time, so a solution that drives the LED directly from processor pins must make sure that the circuit never turns on all LED - not when running and not during boot or when the processor is held in the reset state.

Rule #1: Do not post ideas you might want to patent on a public forum.
It's just about as daft as posting personal software registration details. Fortunately, no one around here is that stupid - Hmmm.
Looks like someone's seen your post and taken the patent for it already.

Thanks a lot guys for your help. I didn't find the appropriate software for my purpose.
Here I am attaching here the doc checklist file for my convenience. I want to count how many ticks are documented and how many ticks are implemented in that document.
Ho, what a bumner for the OP :-)
The frustrated inventor in action. Oh, yeah.
Is Salamander Rashtek a modification of Salman Rushdie as in bored troll posting boring posts because of lack of imagination?
first "secrecy": i will patent the idea. do not copy it
then he wants to give us access to his c: drive c:\program files\docs\auditchecklist.doc

PS to the OP: you can get a truly brandom generator by letting a timer run freely and reading it on the "spin wheel" command
