The pulse is like an electronic heartbeat. You can adjust the speed of the pulses or slower by using a screwdriver.
These InnoBits are compatible with LittleBits and LEGO® making them modular and easily expandable. These would work great with the Meet Edison Robot.
Please note the modules are bigger than the LittleBits ones so they don't sit flush but the connectors do hook up.
