Daisy-Chaining

Daisy Chaining allows you to connect EV3 Bricks together using EV3 USB Cables. You can then use the first EV3 Brick in the chain to control the motors and read the sensors of the daisy chained EV3 Bricks. Up to four EV3 Bricks can be daisy chained.

Select the Daisy Chaining check box on the Project Properties Page to enable Daisy Chaining.
Daisy chaining the EV3 Bricks
The USB Port on the side of the first EV3 is connected to the mini USB Port of the next EV3 Brick using an appropriate USB cable. The PC Port of the next EV3 Brick in the chain is connected to the USB Port of the previous EV3 Brick, using an appropriate USB cable.

Using the Layer Selector
When Daisy Chaining is enabled, each Motor Block and Sensor Block is modified to include a Layer Selector.



Use the Layer Selector to choose which EV3 Brick the programming block will run on.
Examples
The program below makes the Port B and Port C motors connected to the third EV3 Brick in the Daisy Chain drive forward.



The program below drives the first EV3 robot and the second EV3 robot in the daisy chain forward at the same time.
