Arduino starter kit Zoetrope DC motor only humming

Help My DC motor is not spinning only humming I checking my wires battery Code the whole breadboard 3 times and I cannot find the problem that's causing it.

does the motor run when you connect the motor to the battery directly without the arduino. The notch on the L293 must be as shown as pin1 and 16 are that end. The 9 volt battery does not power the arduino it must be powered either by usb from computer or thru the power jack with ac adapter made for or modified for the UNO.
