Introduction: The Rainbow LED Rotator Robot
5-10 different color LED's
Appropriate LED holders
1 DC motor
2 on/off switchs
2pcs 9v battery
9 v battery connectors
Glue gun with glue sticks
you can buy sets which cost less than 8 dollars
Step 1: First We Are Going to Make Support and Placement
Take the cardboard and cut it into 2 circles. Join the circles with some sticks and fit a motor in between them,and attach the cardboard facing the motors spinning edge and attach a CD there.
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.
Step 3: Working Robot
You can use any color LEDs you want
but remember you will need the appropriate resistors
here is a video and some pictures when its done
