Adafruit Gemma M0, Trinket M0, Trinket Mini or Gemma v2 microcontroller board (if Trinket, either the 3.3V or 5V type works).The circuit can be expanded into a number of useful projects. If you turn the potentiometer, the servo will rotate from zero to 180 degrees. Luckily Adafruit supplies a library for interfacing with a computer as a keyboard so the first. A true hardware library would be best if one could be coded, although it would be limited to pins capable of hardware PWM (GPIO #1 and #4). I will be using the 5V Adafruit Trinket and a micro USB cable for this, that’s about all you need. Please be positive and constructive with your questions and comments. But if the strips are Neopixels (WS2812), you will need a level shifter as described above. The library is not ideal, in that servos must be refreshed periodically. Re: Does Trinket M0 work with 5V LED Strips Yes, that will work. Perfect for when you don't want to give up your expensive dev-board and you aren't willing to take apart the project you worked so hard to design.

We wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation.

Fortunately the Adafruit_SoftServo library works well on any available pin (a hardware PWM (pulse width modulated) pin is not required). Trinket may be small, but do not be fooled by its size It's a tiny microcontroller board, built around the Atmel ATtiny85, a little chip with a lot of power. The standard Arduino IDE servo library will not work with 8 bit AVR microcontrollers like the ATtiny85 on the Trinket and Gemma due to differences in available timer hardware. This project demonstrates the use of a standard hobby servo with the Trinket. The Adafruit Trinket's small size makes it ideal for lightweight or small projects including robotics.
