Introduction
The RFD77402 uses an infrared VCSEL (Vertical Cavity Surface Emitting Laser) TOF (Time of Flight) module capable of millimeter precision distance readings up to 2 meters. It's also part of SparkFun's Qwiic system, so you won't have to do any soldering to figure out how far away things are.

In this hookup guide, we'll first get started with some basic distance readings, then we'll add in a confidence value to ensure the sensor isn't returning "garbage" data. Finally, we'll increase our sample rate to obtain readings as fast as we can.
Required Materials
To get started, you'll need a microcontroller to, well, control everything.
