I am new to building, programming Arduino projects as I assume many of us are. Glad to find a place to find information and exchange ideas. I have decided my first project build is a lock operated by a keypad and thumbprint scanner for redundancy. I am using an Uno r3 and I have built some of the circuits on breadboards first; then soldered on to silicon. That seemed like the most straightforward part. My first problem has come with programming the sensor, I am unsure how to program the sensor to send an out put to the lock that I assume is a hi or low to deactivate it. I have loaded the correct libraries for the sensor of course, and used the enroll sketch to capture a print that I confirmed with an LED and the serial monitor. Of course once I get pat that I can work on the keypad. My question would be does anyone have a direction they could send me for how to program the outputs of these. Is it a simple Output pin high or low command after a positive match per se?
