HeadLight with ATtiny13 core

Vexilurz (c)

This repository for create flashlight using ATtiny13 (DIY).

• Idea from: https://geektimes.ru/post/255004/
• For ATtiny13 support in Arduino IDE: https://github.com/MCUdude/MicroCore
• Library for interrupts support: https://github.com/NicoHood/PinChangeInterrupt

How to program ATtiny13 via "Arduino as ISP":

In Russian

• Install ATtiny13 board support using MicroCore
• Load "ArduinoISP" example sketch
• Remove comment in line #define USE_OLD_STYLE_WIRING
• Swap comments on lines #define SPI_CLOCK
• Define baudrate 250 instead 19200 #define BAUDRATE 250
• Program Arduino
• Connect ATtiny13 to the Arduino like in picture below
• Choose ATtiny13 in Arduino IDE boards
• Choose Arduino as ISP (slow) programmer
• Burn bootloader
• Return baudrate to the programmer (19200 instead 250)
• Now you can program ATtiny13 via Arduino as ISP (not slow!) programmer
• (Don't forget to install PinChangeInterrupt library for this project!)

If it don't work - try to pullup RESET pin to the VDD via 10kOhm resistor. You don't need external pullup to the button - ATtiny have internal pullup.
