Introduction: 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. 

Step 1: List of Materials

The list of materials is the following:
1 Prototype Board
1 Green Display CA
1 7404
1 IC-socket 14-pin

This would be handy for a project that I am working on. I have more than enough spare parts I am going to make this now. :D

Logic Probe w/display by itself doesn't need a power supply, but it takes voltage from the electronic device's power supply under probe. However, with this power supply included in your project, you can provide voltage to your circuit that you are probing. Then you have two in one.

You should try the free software Fritzing to create the schematics. Great project by the way!

I've a question for you. Is the software extensible for more components and how to edit them? That is, more IC's 74xx or resistors, etc. Thank you beforehand for your help that you can give me.
Sincerely,
Braulio777

Sorry that I can't provide you with that information but you can try to contact the creators of the software. I suggested the software so that you could create a nice schematic of your project.
