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.
You should post errors and code in < CODE > blocks... like this...
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
Verify your USB cable is a DATA cable (most are power only).
Verify you have your board and port selected:
IDE >> TOOLS >> PORT >> your port
IDE >> TOOLS >> BOARD >> AVR BOARDS >> your board
IDE >> TOOLS >> PROCESSOR >> (if you have a Nano clone) OLD BOOTLOADER
And... did you need to install the CH340 driver? (Nano clone with CH340 chip)
