The Chameleon is built from the Lego Wedo 2.0 educational kit. A tilt sensor is installed on the chameleon’s tail, which, at a certain turn of the tail, gives a signal to start work: the motor starts and, through a worm gear, transfers the movement to the front paws of the chameleon. You can also program the color change of the smarthub indicator using a random number generator.
The set includes step-by-step building instructions and an example of program (in Lego Wedo 2.0 environment).
