Concept
It times how long a VCSEL IR pulse takes to bounce back.
A little theory
ToF ≠ ultrasonic. Works on angles and some sunlight; eye-safe class 1 laser. In the classroom, treat VL53L0X Time-of-Flight Ranger as a intermediate part using I2C. Typical India street price is about ₹180–₹400. Always verify voltage and pin labels on your exact module — silk screens vary across clones. Start with a datasheet or trusted learn guide, power the part correctly, share GND with the MCU, and test with a simple blink/read sketch before building the full project. Measure voltages with a multimeter when something fails, and keep actuator current off the MCU regulator.
