Diy light following robot

This is  a easy light following robot.

Prts you need:-
1.transistors bc 547 -2pc
2.variable resistor 10k -2pc
3.light dependent resistor -2pc
4.pcb
5.battery (i use 3.7v)

Step1:-take a pcb and fix all components according to circuit carefully. 

step2;-here is the circuit diagram basically it is electronic transistor switch

step3;-solder components according to circuit diagram carefully

step4:-this is the circuit (without sensors)

step5:-Add ldrs to both channels

step6:-Time to use our diy robot chassis.add that circuit on it.

step7:-Thats it have fun with it.

thanks :)

DIY ROBOT CHASSIS

                

        HERE IS MY STEP BY STEP INSTRUCTION OF MAKING DIY ROBOT CHASSIS.

  PARTS YOU NEED:-

                 1.       ONE DVD/CD CASE

                 2.    FOUR BO MOTORS

                 3.      FOUR WHEELS

                 4.     WIRES FOR CONNECTION

  STEPS:-

•           TAKE A DVD/CD CASE AND DETACH IT

•                  TRANSPARENT PART WILL BE OUR BASE

       

•                  FIX FOUR MOTORS ON IT

               

•                      IT SHOULD LOOK LIKE THIS

•                     FIX ALL FOUR WHEELS

•               MAKE EACH SIDE AS ONE CHANNEL 

•                   ADD THE BLACK SIDE OF DVD CASE AS TOP

•        HERE IS THE COMPLEATE CHASSIS
