Building a Customizable Countdown Timer with Arduino and 3D-Printed Frame

A countdown timer built with an Arduino Uno, a seven-segment display, IC driver 7447, and a variable resistor offers precise time management. Utilizing three push-to-on buttons for start, pause, and reset functions ensures user-friendly operation. The timer's functionality allows for customizable time intervals from 0 to 99 seconds, adjusted via the variable resistor. A clear LED indicator communicates the timer's current status, enhancing user awareness. This innovative setup not only showcases the versatility of Arduino-based projects but also demonstrates practical applications in various domains, from cooking to industrial processes, fostering efficiency and productivity.
