## Description

Design a clock, timer or counter into your next project using Adafruit's pretty 4-digit seven-segment display. These bright crisp displays are good for adding numeric output. Besides the four 7-segments, there are decimal points on each digit and an extra wire for colon-dots in the center (good for time-based projects).
 
 These are ultra bright 150mcd! You can drive these with less current to get the same brightness to save power, or crank them up to 20mA and have them really bright.
 
 These displays are multiplexed, common-cathode. What that means it that you can use a [74HC595](https://core-electronics.com.au/74hc595-shift-register-3-pack.html) or just 8 microcontroller pins if you can spare them to control the 8 anodes (7-seg + decimal) at about ~15mA each, and then connect [NPN transistors](https://core-electronics.com.au/npn-bipolar-transistors-pn2222-10-pack.html) or a [TPIC6B595](https://core-electronics.com.au/tpic6b595-high-power-shift-register-tpic6b595.html) to the cathodes to sink the 8\*20mA = ~120mA maximum per digit.
 
 These come in a bright white color, [We also have many other sizes and colors!](https://www.adafruit.com/category/37_103)
