Hi, im trying to use a JM-101B fingerprint optic sensor. I downloaded the Adafruit fingerprint library and when I try to upload the enroll example onto my Arduino Nano board I get an error: "avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00"
Can anyone help with this, I have tried it on my mac and windows laptop and the same error is on both. The cable is okay I think and it shows my port on both devices. I only have the one sensor so I have not tried it with another sensor.
