Introducing the "6-character alphanumeric LED Arduino shield"
This shield offers a quick way to add alphanumeric display capabilities to your Arduino project. It is based on the 14-segment 6-character LED display driven by two multiplexed MAX7221 drivers, through a method described in this application note.
The kit includes:
The board has a small prototyping area for adding project-specific parts, for example buttons and buzzer if you want to build an alarm clock (basic clock code for this shield here). Assembled, showing the time (from wsduino):
or, displaying text:
The shield uses Arduino pins D3, D4 and D5.
The kit includes:
- PCB
- 2 x MAX7221 + 2 x 24-pin sockets
- 6-character 14-segment common cathode LED display
- 2 x 33k resistor
- 2 x 100nF capacitor
- machined header (as socket for the display)
- male header (for the shield)
