Seven-Segment Bluetooth Scoreboard Build
Budget: ₹600 – ₹1,500 INR
The project is a compact yet eye-catching digital scoreboard that combines classic seven-segment numerals with modern Bluetooth audio. It must show game scores for two teams on large 1.8-inch red seven-segment modules (00-99) while a smaller four-digit seven-segment display counts down or up as a timer.
Scoring feedback is both visual and audible: every score increment should trigger a short buzzer tone from an integrated loudspeaker, while a second, separate speaker plays background music streamed from a phone via Bluetooth. Control is simple—two push-buttons raise each team’s score and a third button resets both the score and the clock.
The unit will run from a plug-in power adapter; no battery management is required. All electronics, displays, buttons, and speakers need to be housed in a durable metal enclosure with neat cut-outs and standoffs so nothing rattles when the buzzer or music plays.
I need a complete solution covering electronics, firmware, and mechanical integration. Please design the schematic, PCB, microcontroller code (Arduino or similar), and the basic 2-D drawings or STEP files for the metal case. Provide a tested parts list and clear assembly instructions so I can reproduce your prototype.
Acceptance criteria
• Smooth, flicker-free display of both scores and the timer
• Score buttons respond within 100 ms; reset clears all digits instantly
• Audible beep on every score change; volume adjustable via on-board trimmer or software setting
• Stable Bluetooth music playback without interrupting the buzzer tone
• Safe operation from a 110-240 V plug-in adapter with onboard 5 V or 12 V regulation
• All design files (schematic, Gerbers, firmware source, 3-D case files) delivered in editable format and ready for manufacturing
