Simple Selector

Postby rocknrollkat » Fri Nov 10, 2017 10:57 pm

Hi Gang,
It's been a while, but I'm back with another handy dandy problem solver.
I needed a selector that would light LEDs in sequence while turning off the previously lit LED.
Similar to 'radio buttons', this schematic uses a rotary pot to select the LEDs.
After struggling with logic gates, boolean math, etc., I went back to basics and came up with this dead simple solution.
Open up the schematic and see what's what.
You can increase the number of LEDs in the array or have the outputs trigger different modules in your schematic.
Careful with increasing or decreasing the step count, the pot has to deliver a round number to the comparators.
Have fun and I hope this helps out others.

Bill P.
