@seveibar I have added schematic circuits for and and or gates.Can you check and verify this? https://stackblitz.com/edit/tscircuit-ttl-and-or-gates?file=lib%2FMyCircuit.manual-edits.ts

[seveibar]

Hey @Niharika0104 that's pretty great work, but we need to do a couple things to make this a tutorial:

• [ ] Create the AND gate snippet on https://snippets.tscircuit.com using a TTL chip imported from JLCPCB
  • [ ] Use pushbuttons (e.g. @tsci/seveibar.push-button from the import menu) to allow setting each signal
  • [ ] Showcase each input and output symbol with an led
  • [ ] Ensure the 3d preview and PCB preview fully routes
• [ ] Write a markdown tutorial file in the docs repo (this repo) that explains how it was created with screenshots of the 3d preview and schematic preview.

Same for the OR gate. I can't say that this is an easy issue at the moment, but we do plan on creating a lot of issues like this as we go! (So hopefully there will be more examples of people completing it!)

@seveibar I'm trying to add two examples, one for an OR gate and another for an AND gate, but I'm encountering an error that says I can't have multiple manual-edits.tsx files. It seems that a single project can only accommodate one circuit diagram. Am I correct in this assumption? Are you okay with me creating one Stackblitz project to demonstrate the AND gate and another project for the OR gate?

[seveibar]

@Niharika0104 so stackblitz currently uses a really really old version of tscircuit, so to be clear stackblitz projects aren't acceptable generally for this task. The code has to run on https://snippets.tscircuit.com because the CLI that runs on stackblitz is very out of date.

[seveibar]

Also note that that AND gate and OR gate would be separate snippets. This may be a difficult initial bounty.

[Niharika0104]

@seveibar So you want me to demostrate the examples on https://snippets.tscircuit.com/ not on stackbliz??

[Niharika0104]

@seveibar https://snippets.tscircuit.com/editor?snippet_id=cec8bae1-0afc-44c5-89af-7a7b35b836b7 I made AND Gate circuit If you are okay with this,I will go ahead and create a similar one to OR gate as well.

@Niharika0104 I guess i don't really get your AND gate, shouldn't you have like two push buttons, and if someone presses BOTH of the push buttons a light turns on or something? You have a chip in there but there's no input to it.

Let's make it so...

• There are 2 push buttons
• There are 4 LEDs
• There's a USBC connector for power
• There's an AND logic chip (that is popular and in-stock, probably from texas instruments)
• When BUTTON1 is pressed, LED1 turns on
• When BUTTON2 is pressed, LED2 turns on
• When BUTTON1 and BUTTON2 is pressed, LED3 turns on because of the AND gate
• When there is power (USBC is connected) LED4 turns on
• The schematic is readable (not everything clumped)
• The PCB has no errors

I have reduced the scope of this issue and the bounty to only the AND gate (the bounty $$$ is the same, but the scope of the issue is decreased to get the bounty. We will do the OR gate as a separate bounty)

[seveibar]

@Niharika0104 you may want to reference the USBC Flashlight

[Niharika0104]

I will add them.Right now I'm using this IC7408 from jlcpcb(this is also an AND gate). I will do the changes and get back to you.
