3 v, DC ( 2 AA bats.) 6 chasing LEDs. I want then to chase in an 8" circle. Am familiar w/ Radio Shack LEDs & Flashing LEDs - but want sequencing rotation for small projects. Newbie to hobby / want more. Thanx.
Have seen this post before. Very good. Simple & effective. Any mods needed to make it 12v. ?? AND - will it be possible to run two LEDs off of 2-3 pins instead of just one ?
I selected low voltage ICs for the projects. It can be completely re-designed to use higher voltage ICs.
An ordinary CD4017 can drive LEDs when they have current-limiting resistoprs. the CD4017 can be driven from a simple oscillator without the logic I used to make each LED blink for a very short time and have a pause in the chasing to reduce power consumption.
