To be more precise, the circuit seems to wok without the motor connected. when i conencted the motor, then the LCD screens shows very low numbers, and the motor might turn just for 1-2 seconds, otherwise it makes a noise, I guess thats my 2000hz
Just one time the motor turned on and changes direction 3 times very quickly.

Should my power supply for the L293 be different then for the pic ?
