The Fire Truck is built from the Lego Wedo 2.0 educational kit. Fire truck can move forward and backward due to the bevel gear. A hand-operated worm gear lifts the ladder. In turn the tilt sensor activates siren in appropriate position. Additionally, while moving, the indicator of smarthub blinks red.
The set includes step-by-step building instructions and a example of program (in Lego Wedo 2.0 environment).
