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 →Atmega328P Bootloader programmed chip Arduino Compatible - The ATmega328P microcontroller has 32 KB of flash memory for storing code (of which 0.5 KB is used for the bootloader), 2 KB of SRAM, and 1 KB of EEPROM (which can be read and written with the EEPROM library). It can run at clock speeds of up to 20 MHz. Below we shared more information Atmega328P Bootloader programmed chip Arduino Compatible
The Atmega328P is a microcontroller chip that is compatible with the Arduino platform. It is commonly used in Arduino boards such as the Arduino Uno.
The Atmega328P chip is fully compatible with the Arduino platform, which means that it can be used with the Arduino IDE and can run sketches written for the Arduino Uno or other Arduino boards.
This allows for a large community and a variety of libraries and tutorials which makes it easy to use.
Inside every standard Arduino development board is an ATmega 328P microcontroller giving away instructions to its every part. This item is perfect if you plan to create your own Arduino from scratch or you want to replace the broken microcontroller on your board. It already has a bootloader on it which is programmed using Adaboot, Adafruit's own bootloader software. It works just like a standard bootloader with the baud rate set to 57600 for fast uploading. The bootloader is compatible with any NG, Diecimila, Duemilanove, UNO, and other clones as well, and will auto-reset when used with version 009 of the IDE software, or later.
