LaserPING Rangefinder Module

here's a demo of the calibration command for the laser rangefinder module right now I just have the module connected to a USB to serial adapter which is connected directly to my PC that has a the parallax serial terminal running on it for every laser rangefinder module because of the manufacturing tolerances of the laser diode and the camera we need to do a calibration step to calculate the slope and intercept values that we're going to use to help determine range from the module to the target object so in this case I'm using the wall for calibration distance and what I'm going to do is connect up to the to the device and I have the coal and I'm ready to go I'm going to hit X which starts the calibration routine it says set L RF to distance of 20 centimeters and press any key or X to abort so basically I run through a number of different distances in the calibration routine right now cy
