Servo Driven 7-segment Display - Sneak Peek

7 segment display using micro servos rather than LEDs. This is a one digit prototype. The final product is a clock so it will have 3 digits x 7 segments 2 segments for the leftmost digit = 23 servos! The cool thing is that I figured out a way to drive all those servos using nothing more than an Arduino Uno and some transistors. Each additional digit only require one transistor and one resistor. No shift registers, no servo shields.
