Arduino Countdown Timer HobbyTronics
Arduino Countdown Timer. Here is a simple example of how to connect up a 4 digit 7 segment display to the Arduino UNO board and make a countdown timer. The display starts at a predetermined value and counts down every second. When it reaches zero, the display flashes. You can easily add a buzzer to give an audable indication.

Build LED Digits Ninja Timer: Giant 7 Segment Display
To get data from the Arduio and level shifter to the NeoPixels, you'll solder on a 3 conductor JST SM connector to the open end of segment F. You'll connect the center wire will to the DIN pin, with one outside wire going to GND and the other to 5V.
Introducing a 4 digit 7 segment display for a digital
In Chapter 2, Make Your Own Countdown Timer, we learned how to use a 4 digit 7 segment display and build it as a countdown counter. Now we try to build a digital clock using this module. The algorithm for displaying a digital clock is easy, and is as follows:
