Description

A seven-segment display kit: 24 single digits and 12 shift-register driver boards with the resistors already fitted. For clocks, counters, timers and meters.

Highlights

• 24 digits, two kinds. 12 common-cathode and 12 common-anode 0.56-inch red digits.
• Resistors fitted. Each 74HC595 driver board carries its eight series resistors, so no loose resistors to wire.
• Three wires for any length. Daisy-chain the driver boards and drive every digit from Data, Clock and Latch. Works with the Arduino shiftOut() function.
• Snap-on enclosures. Each digit gets a printed frame and smoked film for a finished look.
• Know the limit. The 74HC595 is rated to 70mA across the whole chip, which matters when every segment is lit.
