Applications:

• Events Counter
• Queueing system

PCB dimensions: 162.56mm x 91.43mm

What makes it special?

• It’s a low-cost 3 digits up and down counter that can be operated with Android phone (SCORE3 and SCORE3B apps) and RF remote control.
• The size of the seven-segment display makes it special. The display is large enough to be seen from 10 meters. It is suitable for indoor applications

How is the 3 digits up/down counter built ?

It is a combination of Scoreduino-A and 3 x single digit driver. You can build 3 digits up and down counter using these two devices.

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 SCORE3 and SCORE3B apps. There are two apps designed for this scoreboard.
   • • SCORE3 app can connect to two display simultaneously. If you use SCORE3, the numbers displayed are not reset even if the Bluetooth is disconnected.
     • Score3B works like SCORE3 and it displays the count on the app interface also. If you use SCORE3B, the numbers displayed are reset if the Bluetooth is disconnected.

Power supplies:

1. The 2.3″ up/down counter works with 9V power supply

How does it work?

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

1. SCOREDUINO-A This is an Arduino based controller that sends up and down commands to up and down counters. The schematic of SCOREDUINO-A.
2. Single-digit up and down counter module: I have described how 74LS192/CD40192 based up and down counter modules work. You need to combine three of the single-digit counters and connect them to SCOREDUINO-A. The schematic of single-digit counter is here.

Package includes:

• 1 x 3 digits up and down counter with 2.3″ RED displays

Power supply is not included. We will recommend the right one.
