3-Digit Up-and-Down Counter Based on Scoreduino
The 3-digit up-and-down counter, powered by Scoreduino, is a versatile and user-friendly device designed for a variety of counting applications. Scoreduino is a custom Arduino board specifically engineered to create and operate up-and-down counters and digital scoreboards. This counter model can be managed using SCORE3 and SCORE3B apps or through an RF remote control.
Features:
- Advanced Digital Counting: Utilizes 74LS192/CD40192 ICs for accurate 3-digit digital up-and-down counting.
- Display Sizes: Available in two sizes: 2.3″ and 3″. The 2.3″ model operates with a 9V power supply, while the 3″ model requires a 12V power supply.
- App Control: Can be controlled via SCORE3 and SCORE3B apps. These apps allow users to send specific numbers to the display. For example, sending “468” from the app will display “468” on the counter. The apps also provide buttons for increasing or decreasing the count.
- RF Remote Control: Offers additional convenience with a 4-channel RF remote control, enabling users to adjust the count remotely.
- Bluetooth Communication: Uses Bluetooth to communicate with the SCORE3 and SCORE3B apps, ensuring reliable connectivity.
- Programmable: Can be programmed with an FTDI basic breakout board, allowing for customized functionality.
- Simultaneous Control: SCORE3 app can manage two display boards simultaneously, maintaining the count even if Bluetooth connectivity is lost.
- Resilient Display: The display retains its count even if the Bluetooth connection is interrupted.
Applications:
- Event Counters: Ideal for tracking scores or participant counts in various events.
- Queueing Systems: Useful for managing queues in places like ticket counters or service areas.
Specifications:
- PCB Dimensions: 162.56mm x 91.43mm
- Power Supply: 9V for the 2.3″ counter, 12V for the 3″ counter.
What Makes It Special?
This up-and-down counter is cost-effective and can be operated using either an Android phone with SCORE3 or SCORE3B apps or an RF remote control. The large seven-segment display ensures visibility from up to 100 meters, making it suitable for various indoor applications.
Construction:
The counter combines a Scoreduino-A board with three single-digit driver modules to create a comprehensive 3-digit up-and-down counter.
Supporting Modules:
- RF Receiver and Remote Control: Uses a basic 4-channel RF module and remote control for convenient command sending.
- Bluetooth Module: Allows for control via SCORE3 and SCORE3B apps. The SCORE3 app supports simultaneous management of two displays and maintains the count even if Bluetooth is disconnected, while SCORE3B mirrors this functionality and displays the count on the app interface but resets the count if Bluetooth is disconnected.
