hi guys
i resently bought a 2m led strip ( mono chromatic analog led strip )
and i was wondering if i could build a chaser circuit for it ?
i already saw something like it on youtube :
i don't think a digital write - delay will work , it will blink the whole strip ?!
any help will be appreciated .
For such effects a digital LED strip is required, with individually controllable LEDs.
What you see in the video is probably [u]NeoPixels[/u] (WS2812's).
NeoPixels are RGB (multi-color) and serially addressed and it only takes power, ground, and one data-signal wire to address/control whole strip... Super easy to wire-up! The data-timing is "critical" but there are software libraries so the programming shouldn't be too difficult.
If you have "regular" LED strips you could make a chase effect with multiple strips (or you could cut your strip into smaller strips). But, that's not as "cool" and it requires more electronics, especially if you have RGB strips. i.e. A 4-channel single-color chase light would require 4 MSOFET drivers and a 4-channel RGB version would require 12 MOSFET drivers.
With 4-channels, you're not limited to 4 strips or 4 lights... You can have multiples of 4. The old theater chase lights were usually 3-channels. But, it's not as advanced as multiple individually-addressable LEDs/lights.

No.
