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 →A membrane keypad is a great place to begin any Arduino project that requires the inclusion of buttons, whether for menu selections, robot control, or passwords. Keyboards are perfect for many DIY electronics projects because they are relatively inexpensive, durable, and even waterproof.
It is composed of a thin, flexible material with six layers, each of which serves a specific purpose. Fixing each layer to make this keypad work, and ready to use.
And at last, there is a connector to connect with the device.
