Scoreboard Upgrade With Mobile Control

Our sports venue runs on an ageing electronic scoreboard built around seven-segment LED and P10 LED panels. It still works, but erratically, and it can only be operated from the hard-wired control box bolted under the grandstand. I need the whole system modernised so I can walk onto the field with a phone or tablet and run the show from there. Scope of work • Inspect every board, power rail and driver on the existing hardware, replace any damaged or obsolete parts, and leave the display fully refurbished. • Design and build a new controller unit that adds rock-solid wireless connectivity plus a battery-backup circuit so a brief power loss never blanks the screen. • Write clean firmware for that controller, making sure it can address both the seven-segment digits and the P10 matrix for centre messages. • Create a companion mobile application (Android and, ideally, iOS) that lets an authorised user: – Enter and update scores in real time – Start, stop and reset the game timer – Edit team names and the match title displayed on the centre panel • Implement a secure, low-latency wireless link between app and controller (Wi-Fi, BLE, or another protocol you can justify) that holds up in a crowded stadium. • Deliver an operator interface that is obvious to a non-technical volunteer, with large touch targets and clear status feedback. Acceptance criteria 1. From power-on, the scoreboard must connect to the app within 10 seconds and stay paired for a full four-hour match without dropouts. 2. Score updates, timer events and text changes must reach the display in under 300 ms. 3. During a mains outage the battery backup must keep the display lit for at least 15 minutes. 4. Full wiring diagrams, PCB files, firmware source, app source and a short maintenance guide are handed over at project close. If you’ve rebuilt LED signage, worked with microcontrollers such as ESP32/STM32, and shipped Flutter/React Native apps—or have a better toolchain in mind—let’s get this scoreboard ready for the next season.
