LAB 12 Arduino programming part 2

 In this lab, I read about the photo register and wrote a program that read values. This lab was also hard so I needed extra time to figure out all the lab questions besides lab time.

I connected the 10k register between the ground and one end of the photo register. I used 330ohm, and 10kohm in this circuit, the minimum and maximum range of values was 50~610 when I turned on the flash.

I used the map function that I learned in the lecture to complete this task, the minimum and maximum range of values was 50~610, and I used the map function to turn that into 0~100.

photo register code and circuit

After that, I wired the piezo buzzer and tested the code that was given and finally, I combined the photo register and piezo buzzer and created a single program. I had to use if statements to figure out this question(if it is dark or a button is pressed, turn on the LED AND play a tune. Else, turn the LED off) I had to define if is dark in Arduino, I set up the value of darkness 200. It means Arduino will recognize the dark if is under 200.

Final project(UAS data mapping mission)

Image
Required for the mission:         Mobile device with supporting mission planning software          A UAS Platform/Sensor of your choice I was asked to fly an assigned mission plot at PWA with this parameter. Altitude: 122m Lateral and Frontal Overlap: 80% Use the search function to find and open the Add Z Information (3D Analyst Tools) tool. This tool calculates properties of 3D shapes and appends the result to the attribute table of the input feature class. In this step, you will calculate the length of each sight line. Set the following parameters: Input Features: LOS_Lines Output Property: 3-Dimensional Length      The purpose of this project is to conduct a UAV mission to collect aerial imagery and data for a specific area at PWA(Purdue wildlife Area). The mission area has been assigned and the goal was to fly the assigned mission area while ensuring that the flight boundaries are slightly larger than the assigned area to ensure complete coverage. The Pilot(Jinwook paek) and my v

Volumetric analysis with UAS Data

Image
In a previous lab, I completed some ESRI tutorials regarding raster data analysis. This time, I engaged in raster data analysis using UAS data gathered over the course of a mine dredging operation. I needed to draw upon what I've learned in the ESRI tutorials so far. ·        Extract by mask This tool extracts the cells of a raster that correspond to the areas defined by a mask. The mask is typically a raster dataset where cells with a certain value represent the areas I want to extract. ·          Resample Resampling is the process of changing the resolution of a raster dataset. ·          Surface volume The Surface Volume tool calculates the volume between two surfaces. I began on the 4 th of July to where the mine operation tells of the dredging to take place, and for me to establish a base dataset to know how much material was added. They are also concerned about slope failure and low lying flat areas where water will collect. Because the area flown is pretty large,
