In order for the Raspberry Pi to read the motor's position from the potentiometer, the analog signal needs to be converted to a digital signal. I selected an MCP3002 analog-to-digital converter (ADC) for this purpose. The digital output from the MCP3002 can be read using the SPI or I2C protocols and the Raspberry Pi has built in drivers in the WiringPi libraries for both protocols. I used SPI in the GE320 kit because the driver already existed in WiringPi, which made the implementation very easy.
This year I completed my first teaching certificate through the Center for Innovation in Teaching and Learning at the University of Illinois. Throughout the year, I attended seminars, collected feedback from my students, and had someone observe my teaching. I wrote reflective essays on the entire process as well. I learned a lot while completing the requirements of this certificate. Many of the lessons I was able to apply right away as a teaching assistant, however other lessons I have made note of for future classes that I teach.
The first phase of my dissertation research is to create a laboratory kit that can be used in the introduction to controls course in General Engineering (GE). I have included a description of the course, the existing equipment, the contents of the kit, and a comparison of the laboratory exercises below.
