  1. Results: • Project milestones were assigned as follows: • George: LabVIEW user interface, sensor measurements • Phil: Touchscreen LCD programming, wireless chips • Caleb: Microcontroller programming/interfacing, wireless chips • Each of us worked separately on our respected milestones. Once completed, each milestone was added to the overall project to work together. The microcontroller successfully recorded simulated pressure, temperature and speed readings at a specific rate, and sent those readings to the LCD where it was properly display. The same readings were successfully transmitted wirelessly to a PC with the LabVIEW user interface installed. LabVIEW updated in real time as well as logged the data to an Excel file specified by the user. The overall goal of our project was achieved by being able to take car measurements and sending those measurements to separate user interfaces for displaying and logging without data loss or mismatched values. Abstract: The goals for this project are to implement a data acquisition system for the Formula One racecar built by Bradley University’s Society of Automotive Engineers. Sensors will be installed on the car to collect data for oil temperature and pressure, coolant temperature, RPM, and wheel speed. A microcontroller will convert the data to digital signals and organize it to be sent out. That data will be displayed on an LCD screen mounted to the car dashboard and also wirelessly transmitted to an off-track laptop. The LCD and the laptop will concurrently display the data in real time. The laptop will also have a feature that will save and store the data for further analysis.
