Scoreduino-B Arduino based controller for digital scoreboards

Watch the video of Scoreduino-B

SCOREDUINO-B works with SCORE4 module of Scoreduino app.

The SCOREDUINO-B’ module works as a basic controller for 2.3″, 3″, 4″, and 5″- 4 digits (2 on each side) scoreboards. It has 4 switches for up and down commands for each set of 2 displays.

Other features:

How does it work?

SCOREDUINO-B is designed to work with 2 sets of 2 digits up-down counter. This controller module fits into the female headers of the 2 digits counters on each side. It works with the SCORE4 app. Users can send specific numbers to each set of displays. The communication medium is either Bluetooth or RF or manual control.

An example:

When a user sends 15 to one of the displays, the Scoreduino-B sends up count pulses 15 times to count from 1 to 15, and finally, it stops at 15. All the up-down counters and scoreboards have been designed in that way.

These are the pins on the Scoreduino-B board:

On the left side:

  • 9V: This is to power up RED colored 2.3″ displays. We get this voltage from the voltage regulator LM78XX.
  • 5V: 5V is used for CD4511 and 74LS192 on the left side
  • GND: GND of Scoreduino-B connects with the GND of 2 digits up/down counter
  • A: Send pulse from Scoreduino-B via this pin in order to count UP
  • B: Send pulse from Scoreduino-B via this pin in order to count down
  • 14: Reset pin. Send pulse to reset the count.

On the right side:

  • V: V depends upon the color of the displays used on the right side. For example, GREEN colored 2.3″ display needs 12V. This is the default supply voltage.
  • 5V: 5V is used for CD4511 and 74LS192 on the right side
  • GND: GND of Scoreduino-B connects with the GND of 2 digits up/down counter
  • C: Send pulse from Scoreduino-B via this pin in order to count UP
  • D: Send pulse from Scoreduino-B via this pin in order to count down
  • 14: Reset pin. Send pulse to reset the count.

Scoreduino

What is Scoreduino ?

Scoreduino is a combination of Arduino based controller and Android App designed to operate up/down counters and scoreboards

Scoreduino is an Arduino based programmable controller/device/platform dedicated to building and operating 74LS192 based scoreboards and up & down counters. It is slightly different from the regular Arduino board. It has been modified to make the Arduino compatible with 74LS192. Scoreduino based scoreboards and up & down counters can be controlled with the Scoreduino app.

Types of Scoreduino:

Read about Scoreduino App

Android app for controlling Scoreduino based up/down counters and scoreboards

Scoreduino app is an Android app for controlling Scoreduino based up/down counters and scoreboards. The app has altogether 7 individual apps for different scoreboards and up & down counters.

The app modules are named SCORE1, SCORE2, SCORE3, SCORE4, SCORE5, and SCORE6. There is one more app titled CD4029 which can be used for CD4029 based up and down counter.

The app sends up and down control signals as well as specific numbers to the Scoreduino device.

Scoreduino apps communicate with Scoreduino devices via Bluetooth. It has been built using MIT media lab’s App Inventor For Android. 

The app is FREE and it has been released under a Creative Commons Attribution ShareAlike 3.0 license.
