1) perf board (dummy pcb)
3) encoder ht12e and decoder ht12d ic's, and l293d motor driver or you can use L298N if you are using a lipo or any other high current batteries.
4) rf modules
5) resistances 1M and 51K
7) ic7805 voltage regulator
8) 2 dpdt switches
9) 4dc gear motors
10) any thing to mount your motor and electronics
11) batteries and battery clips.

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Transmitter
make the circuit as shone in he above image
just copy the circuit as it is
it will definitely going to work.
Step 2: Reciever
just connect the data from the reciever module to pin no 14 on the ic. dont get confused
after completion it will look something like this .........which is shone in the above image.
Step 3: Use This Circuit to Convert 9-12v Vcc Into Regulated 5v
if you are giving 9v input to the circuit then u must use this circuit to convert it.
or if you are using 6v directly then no problem.
Step 4: Time for the Motor Driver
my drawing is not good
Step 5: Connect All the Patrs an Enjoyyy
you can use lipo batteries or laptop batteries too cause its too light weight
if you have any doubts, problem or any query leave it in the comments box
make your own and enjoy playing with your bot.
