Roominate rPower is a physical controller that brings girls' creations to life using the Roominate app from their phone or tablet! The small power hub can connect with up to eight circuits simultaneously so girls can control multiple lights, motors, buzzers and sensors on their Roominate creations. rPower is compatible with all Roominate kits and can be incorporated into any Roominate design. With rPower, girls can change how fast or slow a merry-go-round spins, move an elevator up or down, drive a car, turn lights on and off in a house, program lights to blink on a giant Ferris wheel, and so much more!
