Prototype Testing and Data Collection

Problem Statement
According to the CDC, there are up to 13 diseases and 3 parasites that are directly transmitted by mosquitos and their bites. Of up to the 500 million people affected by these diseases each year, over a million of these cases are fatal. Because of the nature of their size, and how widespread they are, this is a worldwide issue.
Introduction
The prototype is assembled, and the code is typed out. At this point, we need to ensure that not only is everything set in its positions, but that we have a plan to make sure that all components are working. The most important aspect that these tests will address is each individual part doing its job. If each component works and functions properly, the result will be more cohesive, and the understanding of the prototype will be much greater.
Test #1: Motion Sensor
Incremental Testing Summary
We will be testing the sensitivity and effectiveness of the PIR Motion Sensor. The LED we attached should light up for a few seconds every time the sensor has been triggered, demonstrating its function ability.
Purpose
The role of the motion sensor is there to trigger the servo and making the prototype a success. Before we can be sure the servo is not the issue, we must find out if the sensor is working as needed.
Pass/Fail Criteria
The PIR Motion Sensor will be a successful component when it triggers the LED when I move my hand in front of the detection range.
Materials
· Arduino
· Computer with Arduino Code
· USB 2.0 Cable
· LED
· Resistors
· Jumper Cables
· PIR Motion Sensor
· Breadboard
Initial Conditions
The room I test in will have no motion disturbances and will have controlled lighting as to make sure we are getting accurate readings from the motion sensor.
Safety Concerns
It is important to have a clear and dry area to ensure no electronics may be damaged or destroyed.
Procedure
· We will have three light levels prepared.
· We will run our hand through the range of detection 5 times.
· We will repeat this test for each light level.
· Record our Data.
Data
· The data we will receive will be determined by the number of successful triggers we get in different light settings.

Test #2: Testing Servo & Spray Can
Incremental Testing Summary
The servo needs to be calibrated to such an angle that it will not damage any of the other materials. The angle should be just enough to trigger the spray can for a few moments and return to its resting state.
Purpose
The contact between the servo and the spray can is one of the most important, because it is what determines how effective the release of the spray will be.
Pass/Fail Criteria
The servo must accurately trigger the spray can successfully and return to its resting state.
Materials
· Arduino
· Computer with Arduino Code
· USB 2.0 Cable
· Jumper Cables
· Servo
· Spray Can
Initial Conditions
The Spray Can and the Servo will be placed as they would in the prototype to ensure there is accurate results when it comes to finalizing the product.
Safety Concerns
It is important to have a clear and dry area to ensure no electronics may be damaged or destroyed. Make sure to clear the path for the spray that might be triggered and take precautions in the event there is flying components.
Procedure
· Trigger the servo at a set angle and observe the results.
· Repeat, but with varying angles.
Data
We will try multiple angles and record whether they worked or not. We will also determine which of these angles allowed the spray to emit the best.

Test #3 Structural Integrity
Incremental Testing Summary
The box holding all the contents must not bend or succumb to the pressure that the servo will be placing on it.
Purpose
Because of the pressure the Servo puts on the Spray Can, we need to ensure that the box we are using can resist the force of the servo so that the spray can trigger will be more accurate.
Pass/Fail Criteria
The Box serves to be merely a container and is not affected when the Servo and Spray Can are triggered.
Materials
· Arduino
· Computer with Arduino Code
· USB 2.0 Cable
· Jumper Cables
· Servo
· Spray Can
· Box
Initial Conditions
All the components will be inside the box and will be performing as they would in the finalized product.
Safety Concerns
It is important to have a clear and dry area to ensure no electronics may be damaged or destroyed. It is important to note that the box may be damaged under conditions placed by the Servo.
Procedure
· Trigger the Servo 10 times.
· Assess the condition of the Box.
Data
We will activate the Servo multiple times and determine the strength of the box with a visual assessment.

Conclusion
I feel as if the approach for assessing each individual part will be the most effective as we are using code and electronic components. It has been a few years since I have used these types of materials, but I feel better knowing I can break down each part and determine the ways to fix and maximize each. I do not believe it will be challenging to test these components just because of how simple I broke down the process. Instead of taking one go at the entire prototype, we can analyze the inner workings of each functionality. When each part works, the entire prototype will work.
