### Lidar lite.(v2)
- 3 Way to use it

#### With PWM pin
- trigger just like regular ultra sensor
- Tested but did not work for some reason.
#### With I2c lib
- Advantage: get continuous reading
- I2c.h only support v1.

#### Todo:
- ask chee town for the 680 uF capacitor to hook up with the lidar
-  currently notthing is working right. check out some lib and reengineering the code to embeded system language
