- Using a MEGA, I could simply use 3 X UDN2981 with a pin dedicated to each segment of each digit (prefer to use a shift register however so as to learn some more).
- Could one use 3 x 74HC595 shift registers to control 3 x UDN2981 - perhaps a bit long winded but again it might be a simpler project for me in terms of learning :-)
