Large Seven Segment Display, 4 inch Digit, Red $19.00 uxcell Common Anode 10 Pin 1 Bit 7 Segment 2.2 x 1.5 x 0.43 Inch 1.8" Red LED Display Digital Tube How to Control a 4-digit 7-segment LED Display with a Max7219 Chip. In this circuit, we will show how to display numerals on a 4-digit 7-segment display using a Max7219 chip. The Max7219 is an 8-digit LED display driver, meaning it can connect to and control as many as 8 digits.

In 2003, CU student Nate Seidle fried a power supply in his dorm room and, in lieu of a way to order easy replacements, decided to start his own company. Since then, SparkFun has been committed to sustainably helping our world achieve electronics literacy from our headquarters in Boulder, Colorado ... A 7 segment LED display consists of 7 LEDs arranged in such a way that it can display numbers from 0 to 9. The arrangement of LEDs in the display can be either common anode or common cathode. In this project, a 4 – digit 7 – segment LED display is used to display numbers using Arduino.
