5-10 different color LED's
Appropriate LED holders
1 DC motor

Step 1: First We Are Going to Make Support and Placement
On the other cardboard circle attach one 9 v battery then attach the cardboard to a CD.Place a switch on the battery somewhere and put an other switch somewhere on the CD with the motor attached and put all the LED's on the CD with equal space between them.then attach the other 9 v battery on the top in between the LED's.
Step 2: Connecting the Whole Robot
To make the soft circuit:-
Connect the battery in between the CD's to the motor and the switch.
Then connect the other 9 v battery to all the LED's and a switch.
Then place the robot with the LED's on the top,
and you are done it is so easy.
