Using the simulator

Introduction

You have arrived at the Magic Forest of Costa Rica. In this place lives a sphere that protects the animals and nature, but its energy is disappearing.
To restore it, we first need to learn how to use the logic circuit simulator.

Basic simulator usage

Before learning about logic gates, we need to understand how to place components and how to connect them correctly.

1. Main interface

On the left side, there is a bar with all available components, such as:

• Inputs (Input)

• Outputs (Output)

• Clock (CLK)

• Logic gates (AND, OR, NOT, etc.)

At the top there are important buttons:

• Edit: mode for placing components.
• Move: move components that are already placed.
• Delete: remove components.
• Save / Load: save or load circuits.

The white area is where you will build your circuit.

First mission: connect an input with an output

Steps

1. Make sure Edit mode is selected.
2. In the left bar, click on Input.
3. Click anywhere in the white space to place it.
4. Then select Output and click again to place it to the right of or near the input.
5. To connect them:
   • Click on the small circle of the input.
   • Then click on the circle of the output.
   • A wire will be drawn automatically.
6. Click on the input symbol to toggle its value on or off:
   • 0 = off
   • 1 = on

If the input is at 1 and the output shows 1, your circuit is working.

What did you learn?

• How to place components (click the component, then click the white space).
• How to connect them using the connection circles.
• How to toggle input signals.
• This circuit does not use logic gates yet, just a direct connection.
