Four Digit Seven Segment Display Module and Enclosure
Although LCDs and OLEDs are popular and quite fancy, sometimes you just need to display some bright clear digits - and this is where this Four Digit Seven Segment Display Module and Enclosure from PMD Way solves the problem.
It's four digits of seven-segment red LED goodness that are controlled via 74HC595 shift registers. The module is both 3.3V and 5V tolerant so works with almost any type of development board including the Arduino Due, Raspberry Pi and so on.
The display is latched, so your code only needs to send data once to keep a value displayed. And you can daisy-chain more than one module together, thanks to the simple serial data nature of the 74HC595 shift register. For complete details, please review the tutorial.
