This is a DIY digital scoreboard for indoor games. All the modules of the scoreboard come fully assembled. You just have to find a way to fix it on a wooden board or make other arrangements to make it beautiful and usable for your sport.

Features:

• Display size: 2.3"
• 2 players/teams Arduino based digital Scoreboard
• Works with SCORE4 app and SCORE4T app
• Send specific numbers to the displays using the app
• When scores are displayed from 0-9, the left digit is off. For example, if a team scores a 7, the scoreboard displays only 7, not 07.
• Bluetooth is the communication medium between the Scoreboard and app
• You can send scores to two Scoreboards simultaneously with the app
• The scoreboard does not reset even if the Bluetooth is disconnected.
• Can be controlled with 4CH RF remote control
• Use switches to manually increase or decrease the count
• 2.3″ scoreboard works with 9V(RED-YELLOW) and 12V(RED-GREEN)
• PCB Dimensions: 2.3″ scoreboard: 250.2 mm* 92.7 mm

To build this scoreboard, we have combined three modules.

• SCOREDUINO_B: This is the central module of the Scoreboard. This is an Arduino-based controller supported by a Bluetooth module and an RF module for communicating with the 2 digits displays placed on its two sides.
• The right display: The right display gets up and down count commands from the central Scoreduino-B controller. The commands can be sent by RF remote control or SCORE4 module of the Scoreduino app. Specific numbers can also be sent to the right display.
• The left display: The left display also gets up and down count commands from the central Scoreduino-B controller. The commands can be sent by RF remote control or SCORE4 module of the Scoreduino app. Specific numbers can also be sent to the left display.

Supporting modules:

RF receiver and the remote control: It uses the basic 4CH RF module and remote control to send commands.

Bluetooth module: The scoreboard can be controlled with SCORE4 module of the Scoreduino app and it communicates via Bluetooth. There are two apps designed for this scoreboard.

• Score4 app without timer controller function
• Score4T app with timer controller function

Power supply: 2.3″ Scoreboards work with 9V

How does it work?

To understand this working principle of Scoreboard, you need to understand two modules:

• SCOREDUINO_B: This is an Arduino based controller that sends up and down commands to up and down counters.

• Single-digit up and down counter module: We have described how 74LS192/CD40192 based up and down counter modules work. You need to combine two of the single-digit counters and connect them to SCOREDUINO_B.
