LED Board

[taconite]

Hey guys,

as I have just 1 Fan output to spare I decided to make a small LED extension board which can control individual addressable LEDs (e.g. Ws2812) with just 1 PWM output from the Duet. This has several advantages.

Components:

• DC/DC converter (from 12/24V to 5V)
• Arduino Nano
• Screw terminals or pin headers

Advantages:

• LED modes (e.g. pulse, running LED, rainbow, ...)
• Just 1 PWM output needed
• With the DC/DC converter you have enough power for the Nano and the LEDs
• Nice integration in the macro system (just set the PWM of the Fan output in e.g. start g-code)

I will order some PCBs so when you are interested - let me know. When the files are final, I will publish them.

I had a similar idea last winter: Imagine, having about 25 different PWM sections in the Nano and using it to not only control LEDs in different modes, but also relays and other stuff in some fashion of a sub-program.

It's no competitor for the developing system using meta-commands and variables, but could be useful to trigger a lot of stuff with just one PWM-output of the Duet.

how did you manage to control it.

My pwm output from heater3 is not stable to do it, and led flirck

@apak sorry I have not seen your reply.

The PWM output is relative stable so I get 18 designated options
