I Built a Sonar Music Player on a Custom PCB | ESP32
I designed and built a custom PCB that combines a sonar distance sensor with a full music player. Powered by an ESP32, the board features an RCWL-1601 ultrasonic sensor, DFPlayer Mini MP3 module, SSD1306 OLED display, 3.5mm stereo headphone output, and physical buttons for control - all on a single custom PCB designed in KiCad #coding #pcb #arduino
