Interfacing PCBCupid's Glyph C6 Board with Adafruit's BNO055 IMU Sensor: A Comprehensive Guide to Motion Sensing and Orientation Tracking
The world of Internet of Things (IoT) applications increasingly demands precise motion sensing and orientation tracking capabilities. From autonomous drones navigating complex environments to wearable devices monitoring human movement, the ability to accurately determine spatial orientation has become fundamental to modern embedded systems. This comprehensive guide explores the powerful combination of PCBCupid's Glyph C6 development board with Adafruit's BNO055 Intelligent Motion Unit (IMU) sens
PCB Cupid: Lighting Up 8x8 LED Matrix Arrays with ESP32 and MD_MAX72XX
After many years spent in the trenches of embedded systems—witnessing the evolution from clunky microcontrollers to sleek, Wi-Fi-enabled boards—I still find a childlike thrill in the glow of an LED matrix. There’s something magical about transforming raw binary into a living, breathing display. Today, I want to take you on a journey through my latest project: bringing the words “PCB Cupid” to life on an 8x8 LED matrix array using an ESP32 and the MD_MAX72XX library. Why LED Matrices Still Matte
