LAB 11 introduction to Arduino

 In this lab, I learned overall Arduino to write simple code to connect analog user input to digital user output. I've never had a chance to learn to code something, so it was first learning coding. I wanted to learn coding because I need to deal with in the future anyway. I was glad to learn this in the lab.

The thing is it was way harder than I thought. The first two parts were easy, all I had to do was to print out hello world. In the first part, I just needed to print out hello world once, so I put code in the void setup and I had to print out multiple times so I put code in the void loop. so far so good

​


The next thing to do was to blink the LED with Arduino and two analog parts using a potentiometer. This part was so hard for me. I had to work on this the other time as well as the lab time. Now that I think about it, it's not a big deal but it was hard for me at that moment. I made a blink LED circuit with a breadboard and put a delay code to blink the LED. I also had to blink with Morse code(( ▄ ▄ ▄ ▄▄▄ ▄▄▄ ▄▄▄ ▄ ▄ ▄ ) So I put different delay codes in Arduino

After that, I created a circuit that connects a potentiometer such that a variable voltage between 0V and 5V is available on the adjustable leg output and I connected the variable leg of the potentiometer to an analog port on the Arduino. I could read the analog signal from the potentiometer. The value was from one to 1023. 

In the analog part2, I added LED in the potentiometer circuit, I made LED show the output(from one to 1023)from the brightness of LED instead of printing in the serial monitor.

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...

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 fai...
