Firstly I would like to apologize for level of noobishness displayed in this question.
I am a HND chemical Engineering student in my final year with no background in science whatsoever, I am a commerce graduate who works part of a Hazmat team for Civil defense. I started pursing the course to better improve my understanding of the work I do and I have managed so far withpout the basics. Now for the final semester I am required to prepare a project. I feel I was somewhat forced into taking Chem e Car for the university. Another aspect being this si supposed to be a group project but none of my classmates made it past the first year so I have been the only one in class for the last 1 year.
A brief description of y project:
My project is adapted from: https://scholarcommons.sc.edu/cgi/viewcontent.cgi?article=1006&context=senior_theses
I am preparing a Chem e Car that is powered by thermo electric generators. I am going to have a hot sink and a cold sink with 6-8 thermoelectric generators placed in between them. This should produce the power to run the car. Now as we are not allowed to use gears my detention mechanism is going to be Iodine clock reaction. Potassium iodide is injected into a container containing Hydrogen sufluide which is initially clear, after a few seconds of injection the mixture will go from clear to blue black. Here I am going to use an LDR to detect the color change and have the car come to a stop upon the color change. I understand the chemicals aspects of the project but I have no idea on the electrical aspects of the project. I had purchased an audrino to control the car. Later someone informed me that I need to have a motor driver as well. Turns out there a lot of specifications of motor drivers and I couldn’t pinpoint which one to buy due to the lack of information on where to start. So if someone could guide me on which motor driver to buy I would really appreciate it.
Along with the audrino I have picked up Darlington transistor, led and LDR’s. Other than the Motor driver would I need to pick up anything else. As my course is for a limited duration I wanted to purchase the relevant materials required for the project so that I can get on ahead to research design and construction of the car.
