Here’s a revised version of your description:
This is a CD4026-based up-counter driver module designed for driving 2.3-inch common cathode seven-segment displays. The module features headers on both sides to receive up count signals and to connect with additional driver modules.
The module can be triggered by various sources, including NE555 timers, flashing LEDs, and Arduino, or any device that generates a clock pulse.
Limitations:
- This is an up-counter only; it counts up and does not count down.
- While it is compatible with Arduino, it is specifically designed for counting up and does not display specific numbers like other drivers.
Applications:
- Event counters
- Object counters
- Scoreboards
- Queueing systems
Why was it made? This module originated from a digital scoreboard project. While designing a table tennis scoreboard, it became apparent that there were no available drivers for 2.3″ seven-segment displays, leading to the development of this product.
What makes it special?
- The large seven-segment display, visible from up to 100 meters.
- Capability to concatenate multiple displays.
- Compatibility with NE555 timers, Arduino, flashing LEDs, or any device generating count pulses.
- Built-in testing circuit eliminates the need for a special pulse circuit.
Pinouts:
- RST: Reset pin
- 9V: Connect to a 9V power supply
- GND: Connect to the ground pin of Arduino or battery negative
- CLK: Input pin for clock pulses
- CO: Pin for concatenating with additional up-counter modules.
