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 →The LM7805/L7805CV is a three-terminal positive linear voltage regulator designed to provide a stable 5 V DC output for electronic circuits and embedded systems. It can accept an input voltage of up to 35 V and provide an output current of up to 1.5 A, depending on operating and thermal conditions.
The regulator uses a standard TO-220 package, making it easy to install on PCBs, breadboards, and other electronic prototypes. It also includes built-in protection features such as current limiting and thermal shutdown, helping protect the device from excessive current and overheating.
The LM7805/L7805CV is commonly used to supply regulated 5 V power to Arduino boards, sensors, microcontrollers, modules, and other low-voltage electronic components. When operating at higher current loads or with a large difference between input and output voltage, a suitable heatsink may be required to manage heat dissipation.
