The Digit Shield is a simple, low-cost Arduino shield that provides a four digit 7-segment display. 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. Soldering required. Arduino not included.
