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 →Are you looking for some mechanism that would help you determine if a bump happened or to control something when a collision occurs? Then this module would help you in indicating those.
This limit switch serves as a limiter for motors and an indicator that you bumped into something.
This module includes a wire that has a male 4-pin JST connector on one end and 4-pin Dupont connector on the other to integrate this with your MCU easily. You could also connect it directly to other DC controlled components.
Note that this limit switch is momentary.
Only one digital pin plus your power supply pins are needed for this module to operate.
