The culmination of EK131, Intro to Hands-On Engineering, involved creating a temperature sensor box. This device was designed to trigger an alarm and illuminate an LED of varying colors based on whether the temperature exceeded or fell below a set threshold. The primary aim of this final project was to apply the diverse skill set acquired throughout the semester, encompassing activities ranging from engineering sketching to practical \ techniques like drill pressing, laser engraving, 3D printing, and soldering.
For this project, a buzzer served to emit an alarm sound whenever the temperature sensor detected readings beyond my set thresholds. However, I opted to add a little spin to my box. Rather than sticking with a standard buzzer, I went on GitHub in search of Arduino source code for the Harry Potter theme song, a beloved series from my childhood. Integrating this musical code into my Arduino IDE made the final results just a bit more fun.
• Organization of solid core wiring inside the container
• Identifying weakly soldered copper wires post heat shrinks using multimeter
• Subsequently, inaccurate temperature readings due to electrical noise and poor voltage connections
• Careful handling of terminals wires due of thin fragile electrical components
• How to convert voltage distruibution to temperature readings using analog code
• Improve soldering techniques and connectivity
• Onshape for the first time
