In this project, I aimed to produce a reliable alternative to the industry leader for under 10% of the cost. I did so using microcontrollers with transceiver capabilities with an attached LCD screen. By transmitting via BLE, there is much less power consumption, which means a longer battery life. This independent project is meant to offer college baseball teams a chance to save valuable funds that would otherwise be effectively wasted. Ideally, these teams would invest the saved funds on more productive ways to improve their team, thus improving the overall level of play in college baseball.en-USPrinceton University Senior Theses
