Simulator

When developing code which interacts with the buttons, light or screen you can use the simulator first.

Motors

The motor section displays information about the motors, the following properties are shown:

• Motor port: A, B, C or D
• Motor ready, displayed as a red or green dot in the motor port circle
• The type of motor represented with an image
• The motor speed and direction displayed as a red bar
• The current motor position

When an EV3 is connected then the motor type which is detected will show up, ports which don't have a motor connected will be empty.

Sensors

The assigned sensor type is displayed in the sensor block, the following sensor properties are shown:

• Sensor port: 1, 2, 3 or 4
• Sensor type represented with an image of the sensor
• The current sensor value

When an EV3 is connected then the sensor type which is detected will show up, ports which don't have a sensor connected will be empty.

If there's no EV3 connected then you can change the value of the sensor to test how your program responds.

The checkbox below the sensors allows you the make the sensor reset to the 0 value after 1 second.

Layers, daisy chaining

With the menu option Daisy chain mode in the EV3 menu you can turn the layers on and control multiple EV3 devices.

If there is more than one layer selected then the layer buttons will be shown above the E3V simulator on the right side of the screen. Selecting a layer will display the motor and sensor output for the given layer on the simulator panel.
