During the summer of 2017, I started working on my first real electronics project. This project marks the first time I have ever seen an electronics project all the way through, from start to finish: initial idea, schematic design, PCB layout, manufacturing, board assembly, testing, device driver development, and full firmware creation.
I love LEDs and interactive toys, so I decided that I wanted to build a top that people could spin to entertain themselves. The PCB would be circular and consist of a single row of LEDs, LED driver, accelerometer / gyroscope and microcontroller (MCU). Having these components would enable the MCU to detect angular velocity while spinning to display persistence of vision (POV) animations on the LED row. I decided to name the project Razzler because blinky LEDs always seem to razzle dazzle. ;)
Since I started this project in the summer of 2017, I figured I’d have working devices by Christmas to give to family and friends as gifts. Little did I know how tall the mountain was that I needed to climb to complete the project… Read on to learn about my journey!
