Directions

• Adding Elements:
      Each circuit must have at least one gate.
1. Click the element to add from the icons. The icon will be highlighted in blue when it is selected.
2. Click where you want to place the element.
3. Click that element again to stop adding it. Note that the blue highlight disappears.
       You can move an element by clicking and dragging it to another location.
• Connecting Elements:
1. Click the small green outlined dot from which the signal will travel.
       Note that you can have up to three inputs to a gate except the Not gate.
2. Click the small green outlined dot to which the signal will travel.
• Erasing Elements:
1. Click the Eraser icon.
2. Click the element you want to delete.
       Note that you can erase any connection line or a gate. When you erase a gate, all connections are also erased
• Running the Simulation:
1. Enter the appropriate values (0 or 1) into the Inputs (w,x,y or z) for the circuit.
2. Click the Run to see the ouput.
       Note there are two possible outputs that can be used. It doesn't matter which output you use for a problem if only one output is required.
• Viewing the Truth Table:
1. Click the Truth Table to see all possible inputs and outputs for the circuit.
• Starting a New Circuit:
1. To start a new circuit, click the Clear button.
