An ESP32 and Eight ToF Sensors Give This Antique Lamp a Sixth Sense

Short summary

A maker converted an antique brass floor lamp into an interactive installation using an ESP32, eight VL53L1X time-of-flight sensors, and a PCA9548A I2C multiplexer. The lamp detects proximity in 360 degrees, brightening LEDs and playing wine-glass tones via a Raspberry Pi as you approach. The writeup includes a scaled-down single-sensor tutorial for beginners wanting to learn the core I2C multiplexing pattern.
