attaching breadboard with chassis

[deepanshu lulla]

sir i am not getting how to attach motor with chassis..i connected one of the wires(black) with ground(top 2nd line) of breadboard..and one (RED) with uln2003..15th pin..

on connecting the battery,led s get illuminated,but  the motor does not work.

there isn't any problem in motor(i connected it separately and tested it)they were working..

i am not getting what is the mistake in my circuit?

U mst connect motol wid d diff. Battery
for that, connect the -ve ternimal of d battery with common ground of
d circuit and connect +ve with one of d terminal of motor
i.e one terminal of motor is connected to uln 2003
N d other wid battery terminal

Try some combinations for forward motion of both d tire according to sensing.

alrite,

you connect the output of the motor to the -ve terminal of a 9V battery and series it with the motor. that should work for u.
