Accelerometer Analyzing Golf Club
This is the homepage for my final project for ECE 387's Toy Embedded System. On top of giving an overview of the project, this page also provides links to useful information as well as videos of the project in action.
Final Outcome & Conclusion
The original intentions for this project were to create a golf club that used an accelerometer to calculate both speed and angle head of a golf swing. Being able to display this information in some user-friendly prompt with, hopefully, a useful graph.
- Golf Club: The obvious essential tool. The development of the system relied upon this
- Arduino Microcontroller: The microcontroller that was intended to analyze the readings from the accelerometer
- ADXL-335 3-Axis Accelerometer: Basic Accelerometer that returns analog values representing the G-Force measurements along the 3-Axis of movement
- Computer Software: Originally, the intention was to use the Arduino's software to analyze the accelerometer readings and MatLab for calculations
- 2 Laser Pointers: Laser system similar to garage door system in typical household
- 2 Laser Receivers: Receiver that outputs HIGH/LOW readings based on light received
Final Outcomes & Conclusion
Unfortunately, I was not able to complete all of the objectives that I set out to accomplish from the start. I discovered that with only one accelerometer, it is nearly impossible to calculate angle head. With two, it would have definitely been doable, but then the cost analysis became slightly harder to justify for a toy project.
I also was hoping to make the system as autonomous as possible. Having the user only interacting with the golf club and not having to save Excel files and execute MatLab files was the goal, but from a prototyping standpoint, I really feel as if my system, was effective.
This project, if worked on somewhat, could be highly marketable. With two accelerometers, 3D imaging is possible, showing the movement of the golf club head through a 3-Dimensional space. More accurate readings for speed are also possible with two accelerometers. Going back to the cost analysis, while prototyping with two accelerometers may not have made sense, in mass production scenarios, two accelerometers will likely become more feasible. This is definitely something to take into consideration for future work.
