why my circuits on breadboard are not working?

after uploading the program to the arduino , my led over the arduino is working according to the code written, but the circuit on the breadboard is not working why?

My hunch is you are missing a connection, perhaps your breadboard LED's connection to ground? Post a photo of your circuit if you are still having trouble.
