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 →Tiny ATtiny85 dev board the size of a coin, with a USB-A plug built right onto the PCB. No cable, no separate programmer. Plug it into a USB port, program it from the Arduino IDE. Great for small always-on gadgets and USB tricks where a full Uno is overkill.
| MCU | ATtiny85 |
| I/O | 6 pins (2 shared with USB) |
| Flash | 8KB (~6KB after bootloader) |
| Power | USB, or 5V / 7-35V external (auto-select) |
| Regulator | 500mA 5V onboard |
| Buses | I2C and SPI (via USI), PWM on 3 pins |
Only 6 I/O and 8KB flash, so it's for small jobs. Uses Digistump's board package in the Arduino IDE, add the board URL first.
