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:

  • 2 players/teams Arduino based digital Scoreboard
  • Programmable using FTDI basic breakout board
  • 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
  • 4″ scoreboard works with 12V.

PCB Dimensions: 4″ scoreboard: 450.8 mm* 147.3 mm

This Scoreboard can be used along with ‘Scoreduino Timer’ also. The following video shows 3″ scoreboard, however, the timer can also be used with 4″ Scoreboard. Please have a look.

To build this scoreboard, we have combined three modules.

  1. 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. Read more about Scoreduino_B.
  2. 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.
  3. 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:

  1. RF receiver and the remote control: It uses the basic 4CH RF module and remote control to send commands.
  2. 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 with timer controller function
Score4 app. You can connect the app to two scoreboards.
Score4T- This app has a controller for timer also. It connects to one timer and two scoreboards

Power supply: 4″ Scoreboards work with 12V

How does it work?

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

  1. SCOREDUINO_B: This is an Arduino based controller that sends up and down commands to up and down counters. The schematic of SCOREDUINO_B.
  2. 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. The schematic of single-digit counter is here.

Package includes:

  1. Fully electronically assembled Scoreboard
  2. 12V Power supply (shipped from third party store)
Display Sizes

2.3" RED(left) and YELLOW(right), 2.3" RED (left) and GREEN (right), 3" RED(left) and GREEN(right), 4" RED(left) and GREEN(right)
