Logic Probe W/display

This project is equipped with 5 Not Gates, 1 transistor, 8 resistors, and 1 Common Anode Display. The Logic Probe w/display is a project for identifying Zero (0) or Low, One (1) or High, or Pulse. For Zero, you will see illuminated the upper side of the display by simulating a "0" (Zero). For One, you will see illuminated the rest of display for forming a "P" without illuminating the upper side of the display by simulating a "1"(1). Finally, for a Pulse, you will see illuminated the display by forming a "P"(Pulse). And so you can detect "0's", "1's", and Pulses.
