3-Digit Up-and-Down Counter Based on Scoreduino
The 3-digit up-and-down counter is a versatile and user-friendly device designed around the Scoreduino, a custom Arduino board tailored specifically for creating and operating digital scoreboards and counters. This counter can be seamlessly integrated and operated using the SCORE3 and SCORE3B apps.
When used with the SCORE3/SCORE3B apps, users can input specific numbers directly to the display. For instance, sending “468” from the app will immediately display “468” on the counter. The app provides buttons to increase or decrease the count, offering straightforward control.
Additionally, an RF remote control can be used to adjust the count, providing an alternative means of operation. The counter is available in two sizes: a 2.3″ display, which operates on a 9V power supply, and a 3″ display, which requires a 12V power supply.
Features
- Digital Up-Down Counter: Utilizes 74LS192/CD40192 for 3-digit counting.
- Display Sizes: Available with either 2.3″ or 3″ seven-segment displays.
- App Control: Compatible with SCORE3 and SCORE3B apps via Bluetooth.
- Remote Control: Can be operated using a 4-channel RF remote control.
- Programmable: Supports programming with an FTDI basic breakout board.
- Simultaneous Display: Capable of sending numbers to two display boards simultaneously through the app.
- Non-Resetting Display: The display retains its count even if the Bluetooth connection is lost.
- Power Supply: Operates with a 12V power supply.
- PCB Dimensions: Measures 211.89mm x 114.29mm.
Applications
- Event Counters: Ideal for tracking counts in various events.
- Queueing Systems: Perfect for managing queues in different settings.
Unique Selling Points
This up-and-down counter stands out due to its affordability and ease of use with an Android phone (using SCORE3 and SCORE3B apps) and an RF remote control. The large seven-segment display, available in 2.3″ and 3″ sizes, is highly visible from up to 100 meters, making it particularly suitable for indoor applications.
