Outside of School Projects
-
pH Regulator/Meter - This project is a solution to regulating the pH of chemical reactions, without requiring a chemist to sit next to the reaction in order to manually measure and make adjustments. I wrote an Arduino program with a peristaltic pump, pH sensor, and LCD screen to read the pH of a reaction and pump in acid/base if the reaction was deviating from the expected pH. I built this project from scratch including both the hardware and software required for the end goal. The step by step process of how I made this project, code that I wrote, and a video of the project in action are included on the Instructables page that I created (link below)​
