Hi, my name is Raymond. I’m debating on wether i should use an arduino or a pololu chip for my project. I’m building an iron man suit and want to make the helmet faceplate to open with servo’s and the eyes light up. I know this has been done with a pololu chip and with an arduino chip. Here’s my question: I would like the led eyes to flicker and than fade on. I know this can be done with an arduino. Like this:http://youtu.be/mNxV7EYeqgM. Is this possible with a pololu mini meastro?
Thank you.
Anyone? Could sure use some advice.
Thanks.
Hello.
You might be able to use the PWM output available on the Mini Maestros to produce a fade effect with your LEDs. You can read more about the PWM output and the Mini Maestro in the Maestro user’s guide. In particular, the “Status and Real-time Control” section explains how to use the PWM output on the Maestro.

Thank you for your help. I will look into it. I am a newbie and never atempted something like this. Is it possible to connect mutiple leds to the PWM output?
Thanks.
It is possible to control multiple LEDs with the PWM output, but all the LEDs will be doing the same thing. You will probably also want to add a transistor to drive your LEDs since the signal pins on the Maestro cannot deliver a lot of current.

Hi Raymond. I built a suit a few years ago around the mini meastro. I posted the code here too.
Good luck
