Using Arduino as ISP Programmer
| Attiny | Arduino |
|---|---|
| Pin 1 (PB5) | D10 |
| Pin 4 (GND) | GND |
| Pin 5 (PB0) | D11 |
| Pin 6 (PB1) | D12 |
| Pin 7 (PB2) | D13 |
| Pin 8 (VCC) | 5V |
First, burn the ISP program to the Arduino:
Open the IDE's preferences and add the following URL to the Additional Boards Manager URLs:
https://raw.githubusercontent.com/damellis/attiny/ide-1.6.x-boards-manager/package_damellis_attiny_index.json
Open the Boards Manager:
Search for and install the package (you might need a proxy):
When burning the bootloader, make sure to select the correct chip model, clock speed (Internal 16 MHz), the port where Arduino is connected, and choose "Arduino as ISP" as the programmer:
