At the very first moment when I was given the capstone project, I thought about the department at university I would like to apply to. I’ve researched a capstone related to biomedical engineering. There were several topics about it that are difficult for me to complete without professional knowledge. So, I concluded that I can still challenge myself related to any engineering field. Finally, I decided to make a digital thermometer from scratch because I noticed that I burn myself almost whenever I use hot water with faucets and it would be my grandfather's problem and others' problem as well.
I’ve learned how to use a breadboard and how to connect each component together for two years in elementary school. I’ve also learned a little about how to do coding when I was in grade 7. Physics 11&12 and Pre-Cal 11&12, which I completed, would help me to understand how many voltages will produce by a temperature sensor and the maximum amount of current that should flow through the circuit by using resistors which are to prevent LED screen from destruction.
Problem-checking and solving were recorded in each producing process on the product page.
Changes:
I didn't buy a small LCD screen to make a smaller version of the first product since the first product has no problem acting as a thermometer.
I didn't make the final case to fit with my faucet but made it to be used as a carriable thermometer.
I could not start using the 3D printer in November. I started working on 3D printing from January to May because I finished building the circuit in January. While I was working on 3D printing, I organized the site. Producing the actual case that fits with the Arduino finished on May 5. After this, I spent the most time making the site and reflecting on the entire process. Thus, I started to use the final project in May.
