Introduction: NAND Gate Logic Using Circuit Scribe

Electroninks shows us how to create AND Gate logic using CircuitScribe. I’d like to add to this with an Instructable replicating my favorite logic – NAND gates. These are by far my favorite logic circuits, simply for the fact that with enough NAND gates you can replicate any basic logic.

All the parts are included in 1 Developer Kit

For this Instructable you will need:

• Circuit Scribe Conductive ink pen
• A sheet of paper
• 1x 9V battery module
• 2x NPN Transistor Modules
• 2x SPST Modules
• 2x 100K Ohm Resistors
• 1x 10K Ohm resistor
• 1x LED module
• 3x 2 pin modules (Note: If you don’t have enough you can clip the 9-10 section of a DIY board module as I have done)
• 1x Steel Sheet
• 1x Circuit Stencil

Optional:

• 2 extra LED modules for testing

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

The above pic is the end result you’re looking to achieve. Trace the individual module’s on a sheet of paper using the circuit stencil and your conductive ink pen. Take note of spacing. Depending on how much room you have you can organize the space as you wish. My circuit diagram is made in the circuitscribe sketchbook so it should be able to fit on A5 and above. I also labelled placeholders for my modules to make future referencing easier

Connect the dots and be careful not to bridge any sections that shouldn’t be bridged! Don’t leave any gaps either

While the ink dries load your resistors into the 2 pin modules if you haven’t already. You can connect resistors in parallel on the 2 pin boards to achieve other other resistance values. If you are using a clipping from the DIY module you may want to bend the resistor legs to ensure they are connected.

When you'e done, place the steel sheet under your paper and place the modules on the board. If you’re using the LED modules make sure you place them before the resistors. You can rearrange the circuit as shown in the next step.

Step 3: Try It Out!

Your NAND logic should work out as follows:

0 0 1
0 1 1
1 0 1
1 1 0

Mine worked like a charm. How did you do?
