[R-B] designed a 555 timer circuit to scan a keypad. Keypads are common interfaces for small projects and require row and column scanning by a microcontroller. [R-B’s] setup allows you to reduce the ...

You can use a microcontroller to build a clock. After all, a clock is just something that counts the passage of time. The only problem is that microcontrollers can’t track time very accurately. They ...

This module allows you to develop a timing system, which utilizes the Arduino’s fast internal clock to provide an accurate timing system for kinematic experiments. Also, this module focuses on how to ...
