I just completed my first FastLED project - a blinky high chair. Thanks to some people in this group for helping me figure out how to assign colors to each button in a way that can be easily stored in an an array. Link to documentation below…

oh my i love this

I really, REALLY like this!!!

That’s great!

Excelent! @Tim_Bartlett
I’m about to build this to my childs. :slight_smile:
I might change the Trinket by a attiny85.
Do you have any suggestion about this?
What do you think is better?
Change the fastled library? or redo the sketch to use it without the library?

I don’t have enough experience programming ICs that aren’t on a microcontroller to say, but I suspect that library will work. Maybe other people in this group could comment? I’m new to FastLED.

Assuming it does run, other than updating the pin assignments, I’d remove line 45 which limits the current draw from the pixels (FastLED.setMaxPowerInVoltsAndMilliamps(5,130):wink: It’s set for the Trinket’s max of 150 mA (minus 5v x 4 for the buttons), but whatever 5v source is powering the attiny can also power the LEDs, and presumably handle more than 150 mA. I normally wouldn’t power the LEDs downstream from the microprocessor, but the 4 AA batteries are too much for the neopixels. I killed one figuring that out.

Please let me know if it does work out – I’d love to do that myself for future projects.

No problem, will keep you updated!
and that line (FastLED.setMaxPowerInVoltsAndMilliamps(5,130) was also in my next question, following your suggestion, I will do it without the current limitation, and isolating the mcu from and protecting the leds. :slight_smile:
