If you ask us, there’s no substitute for learning by doing. But often the hardest part of acquiring new skills is coming up with the idea for a project that utilizes them. [Mike Rankin] wanted to develop a project using laser cut acrylic, and settled on building a control box for an RGB LED strip. He got some practice modeling objects in SolidWorks and seeing the process through to the final build. But it also let him explore an area of microcontroller programming in which he had little experience.
The LED strip he’s using depends on the HL1606. This is an SPI addressable chip that we see popping up in a lot of projects these days. It’s pretty simple to send red, green, and blue values through the data bus, and it allowed [Mike] to try his hand at programming menus and sub-menus. The controller takes input from a clickable rotary encoder. The settings are displayed on an OLED screen, with all the hardware nestled comfortably in his custom-cut enclosure.
