ess of creating a full adder.

Running the simulator

There are 3 ways to get the simulator up and running:

1. Using the version hosted on github-pages:

This is by far the fastest solution - everything you need to do is open the github-pages url

2. Using a development server:

First you need to have node.js & npm and git installed on your machine.

Open a terminal in the desired folder and run:

#  Clone repo
git clone https://github.com/Mateiadrielrafael/logicGateSimulator

# Cd into the folder
cd logicGateSimulator

# install dependencies
npm install

# run development server
npm run dev

3. Building the simulation yourself

First, clone the repo and install the dependencies as explained in option 2.

To build the source run:

# build program
npm run build

To then run the simulation, open a server in the dist directory. A simple solution using npm:

# instal nano-server globally
npm i nano-server -g

# change directory
cd dist

# run server
nano-server

# linux
open http://localhost:5000

# Windows
start http://localhost:5000

Building a 4 - bit adder:

1. Create a new ic called half-adder (Create simulation > Integrated circuit > Half adder)

2. Add the following logic gates (Logic gates > the name of the gate):

   • 2 buttons
   • 2 light bulbs
   • a XOR gate
   • an AND gate

You can get more info about these gates by clicking Logic gates > the info icon at the rght of the gate.

3. To move a gate, drag & drop it with the right mouse button. To connect 2 pins, click once on each. Build the following configuration:

3. Create a new ic called full-adder (See step 1)
4. Add the following gates (See step 2):
   • 3 buttons
   • 2 light bulbs
   • 2 half adders
   • an OR gate

5. Build the following configuration (See step 3):

6. Create a new project called 4-bit-adder (Create simulation > Project > 4-bit-adder)

7. Add the following components (See step 2):

   • 8 button
   • 5 light bulbs
   • 3 full adders
   • 1 half adder

8. Build the following configuration (See step 3):

9. Enjoy! Congratiulations! You've made your first circuit! With this simulator at your dispossal, the possibilities are endless! Here are a few things you can try and create yourself: - A 4-bit substractor - A counter - Different latches - If you are confident in you skills, you can even make a full 4-bit processor!
