Summary of USB BUSINESS CARD WITH ATTINY85
This article describes a compact USB Business Card project using an ATtiny85 microcontroller. The device mimics a keyboard to automatically type pre-stored contact information into a computer's notepad when plugged in. It utilizes the internal 16.5 MHz RC oscillator and V-USB driver software, requiring minimal circuit elements.
Parts used in the USB Business Card:
- ATtiny85 Atmel microcontroller
- 16.5 MHz internal RC oscillator
- USB connector on PCB socket
- Printed Circuit Board (PCB) with 1.6 mm thickness
- V-USB driver software
- Notepad program (host application)
