Tell us about yourself!
Hello again! After trying a friend's Arduino, buying another FPS, and running off a few different computers, I am still running into the same problem. The blink example seems to work fine when the serial monitor is not open. Although, as soon as I open the serial monitor, the text below is output, the FPS stops blinking, and nothing more happens. Any ideas?FPS - OpenFPS - SEND: "55 AA 01 00 00 00 00 00 01 00 01 01"Also, I could be wrong, but I think the placement of the 560 Ohm resistor in the provided above schematic is incorrect. A different image that you provide shows it in the correct position (series with the 1K Ohm). Is this accurate?Thanks!
Thanks greatly for the write-up! I'm having trouble with the FPS. The FPS blink example works when the serial monitor is not opened. Upon opening the serial monitor, the FPS blinking stops. Further, I have been unable to get the sketch that saves a fingerprint to work reliably. Unusually, it randomly did work once. I am using a SainSmart Uno clone, instead of the ATMega 328. Is it perhaps a problem using the SainSmart?
