Thanks guys for your input and suggestions.
I found a simple solution - although it doesn't give me a different pseudo-random for each of the 16 LEDs as I had originally desired, it certainly provides enough variation to give the desired effect (and with 18 LEDS instead of 16).
I used this...
"By far the simplest and cheapest approach is a small microcontroller with 16 output pins. These are very inexpensive. Generate either one 16-bit random number or two 8-bit numbers, whichever is easiest and send the number to the output pins. Connect the cathode (+) end of the LEDs to the output...
Hi all,
I'm completely new to this forum, so I hope I am asking in the right area.
I'm working on building a toy for my 3 year old boy. What I am trying to do is to get 16 LEDs in a circuit to all flash independent of one another at seemingly random rates (probably in the 50-250 ms range) -...
