The Digit Shield is a simple, low-cost Arduino shield that provides a four digit 7-segment display. Choose from 3 different colors: fiery red, cool green, or bright blue.
- An easy-to-use open source library makes it very simple to display integers and floating point numbers.
- Multiplexing of digits is implemented using a timer overflow interrupt handler for flicker-free display.
- Only uses 4 Arduino pins (2,3,4,5).
- All through-hole parts for easy kit assembly.
