Arduino UNO sketch to check response rate for tinyLiDAR

It will run a number of readings as fast as possible and give the effective response rate in Hz.

(showed over 930Hz in our lab testing)

Notes:

This code requires the "Arduino I2C Master Library rev5" library to allow the

standard I2C stretch feature to work properly on the UNO.

** Please install it before running this sketch. **

The library can be downloaded from here:
