Just bought an arduino nano so I could move a servo, I uploaded some code and it went through with no problems, now I'm trying different code but the physical reset button isn't working.
To my understanding it should flash the 'L' light and the PWR light should end up flickering?
However at the moment, the PWR light is always on and nothing changes when I hit reset.
When I try to upload my new code, i get this error:
avrdude: stk500_recv(): programmer is not responding
Any solutions would be greatly appreciated!
Additionally, this was the code I uploaded to the Nano with no trouble:

int buttonState = 0; // current state of the button

// led control pins (need to be PWM enabled pins for fading)
const int leftEye = 6; // the number of the left eye/pcb LEDs
const int rightEye = 3; // the number of the right eye/pcb LEDs
