Frequently asked questions
What is the price of 4-Digit 7-Segment LED Display 0.36 inch Common Cathode 3641AS (Red) in Egypt?
4-Digit 7-Segment LED Display 0.36 inch Common Cathode 3641AS (Red) currently costs 25 EGP in Egypt.
Where can I buy 4-Digit 7-Segment LED Display 0.36 inch Common Cathode 3641AS (Red) in Egypt?
4-Digit 7-Segment LED Display 0.36 inch Common Cathode 3641AS (Red) is available from UGE. Compare the offers above to find the best price.
How do I wire a common cathode display to a microcontroller?
Connect the common cathode pins to GND, or switch them with transistors when multiplexing the digits. Drive each segment pin HIGH through a current-limiting resistor. For 4 digits, enable one digit at a time quickly so all four appear lit to the eye.
How many microcontroller pins does it need?
Driving all segments directly needs about 12 GPIO pins (8 segment pins plus 4 digit-select pins). A shift register such as the 74HC595 or a dedicated display driver IC reduces the number of pins required.
