Introducing a versatile 3-digit up-down counter designed for Scoreduino, a specialized Arduino board crafted for creating and managing digital counters and scoreboards. This counter integrates seamlessly with the SCORE3 and SCORE3B apps, allowing users to input specific numbers for display control. For instance, sending “468” from the app will reflect instantly on the counter. App functionalities include dedicated buttons for increasing or decreasing counts.
Additionally, the counter supports RF remote control for convenient count adjustments. Available in two sizes—2.3″ and 3″—the 2.3″ variant operates on a 9V power supply, while the 3″ variant requires 12V.
