The problem
Shot tracking exists for pro teams, but it costs thousands. Amateur players have no way to know their real shooting numbers.
What I built
I combined an infrared sensor and a vibration sensor on an Arduino to tell makes from misses at around 95 percent accuracy, and streamed every shot over Bluetooth to an Android app I built. Tested with 20 players and around 2,000 real shots.
What it does
- Two Sensors, One Answer. My C++ code matches the infrared trigger with the vibration spike inside a one second window to call make or miss.
- Under 25 Euros of Parts. An Arduino Uno, an infrared sensor, and a vibration module. That is the whole rig.
- Built End to End. I designed the circuit, wrote the firmware, defined the Bluetooth protocol, and built the Android app.
- Tested on a Real Court. 20 players and around 2,000 shots, at about 95 percent detection accuracy.
