Object Counter using VL53L0X & OLED Display

Arduino UNO, VL53L0X Laser Time-of-Flight Sensor & SSD1306 OLED

👁️ Operational Overview System Logic

This automated industrial telemetry station uses an Arduino processing core to run an instantaneous object tracking loop. By acquiring precise real-time laser distance readings via the VL53L0X Time-of-Flight (ToF) sensor, the system dynamically locks and tracks nearby objects. Data values are seamlessly compared against localized proximity thresholds and written directly onto an SSD1306 high-contrast I2C matrix terminal.

Detection Window Limits

📏 Increments automatically under 100 mm

Anti-Double Count Logic

🔒 Debounces state lock until object clears 150 mm
