Fingerprint Sensor AS608 - A Beginner's Guide
One touch can replace keys. This project uses an optical fingerprint sensor to enroll users and then grant access with a quick scan.
read tutorial →Breadboard MB102 830 Point - A breadboard comes in handy when you are organizing your wiring connections. You can use a breadboard if you have multiple sensors attached to your Arduino board.
This breadboard is what we usually called the full-size breadboard. The total number of tiny holes is 830. 200 of which are for power rails on both sides, having 100 each. The middle part where you make the connections of your components are terminal strips, 630 pins. The holes have a spacing of 0.1"/ 2.54mm for jumper cables and headers.
It also has self-adhesive on the back for mounting, and interlocking parts so that you could have a cascaded breadboard. We also have a half-sized version and a mini version.
