99 Decimal Counter Kit

Description:

Explore digital logic, 7-segment display, and counting circuits with this hands-on project. You’ll build a two-digit counter circuit that counts from 00 to 99 at an adjustable speed, with a reset button to return the display to 00. The board uses integrated counting ICs to handle digit rollover automatically, while dual 7-segment LED displays provide a bright, easy-to-read output.

Great for students, hobbyists, and educators, this kit demonstrates key electronics fundamentals in a clear, interactive format. This project is ideal for learning about simple circuits and leveling up your V-One skills. The included components ensure reliable operation and straightforward assembly.

Note: This circuit is designed to work in series with other circuit boards. Check out the pulse generator project (required for the 99 decimal counter to work) and the voltage regulator project (recommended for the 99 decimal counter to work) that connect to this board.
