LED Firefly Circuit Recommendations

[Steve Saunders]

Looking for suggestions on simple circuit w/out using microprocessor to
drive multiple LEDs in a random blinking pattern. The objective is to
emulate a "jar full of fireflies".

Numerous Google searches have yielded some interesting things, but nothing
quite like I envision.

Thoughts or suggestions?

hi steve,

I would say, if you have access to a simple FPGA board, coding a binary
counter in VHDL with some simple logic to randomly select particular
counter bits to drive the LEDs is an easy way of randomly LED
blinking...I hope this helps....

If you dont have access to any FPGA prototyping boards, you can find
cheap and compact FPGA board at www.design4fpga.com .

Regards,
