Volume Knob V2 (USB-C)

myminifactory

An Arduino pro micro project to control volume or mute the sound. You also use rgb to have a nice experience. Regular Mode: Animation-Modes: What do you need: 1 x Arduino Pro Micro(USB-C) blue Version8 x SK6812 LEDs(5050 Chip)1 x ALPS Rotary Encoder with integrated Switch1 x 10k Ohm Resistor4x M3X16 srewsM3 threaded insertsPCBIt will cost around €20 per Volume Knob. If you want to find more information, you can go to my GitHub page. 3D Printing: You can print all the parts from PLA besides the transfuser that should be transparent. (Optional) use the special feature to edit the bottom pattern. I liked the Octagram Spiral that Assembly: 3D print all necessary parts  Next, use a soldering iron to melt the threaded inserts into the top at the marked places.   Assemble the PCB → First the SMD LEDs, after that the resistor. The next step is a little bit tricky, remove the little feet from the rotary encoder and solder the 5 pins to the PCB. The last step is to solder the Arduino Micro to the PCB.   Software:You have a limited amount of control. The software is arranged in a system like on the picture. You have the selection of 25 different colors and 5 different animation modes to choose from.  Program the Arduino with the Arduino IDE
