Exposure to chemical engineering is a critical factor in students' decision to major in chemical engineering. However, many underrepresented minority students lack exposure to chemical engineering outside of formal education. While there are resources regarding labs that could be implemented in high-school and introductory college level courses, few appear to focus on the concept of process control at a high-school skill level or above, and many others are inhibitory for K-12 and first year engineering programs to utilize due to the cost of implementation. To better introduce students to the nature of chemical engineering work within their final high school years or during the first year of their collegiate career, I have developed an affordable PID controller laboratory that introduces students to the process control nature of chemical engineering. The PID controller laboratory utilizes an inexpensive microcontroller and supporting components to introduce students to PID controllers and the use of microcontrollers. Students are expected to run the system at several different tuning parameters to gain an understanding of how the system operates over time. The final price point of this lab sits under 200 dollars and with modifications it can be operated for under 100 dollars. In conclusion, this lab offers an affordable option to instructors looking to introduce the fundamentals of process control with their students.
