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) and a top right hand dot which could be used to indicated a ° (degree) symbol for temperature feedback.

These are ultra bright 160mcd! 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 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 or a TPIC6B595 to the cathodes to sink the 8*20mA = ~120mA maximum per digit.

These come in a bright red color, They also have yellow and green
