The USBTinyISP programmer attaches to your computer's USB port and uses the 6-pin ICSP port on your Arduino to program it. It can program both bootloaders and sketches. It can be purchased for less than $10 from Amazon or Ebay.

There are 3 main options how to write bootloader or program to AVR over ISP.

  1. dedicated AVR programmer or Arduino ISP programmer
  2. other Arduino with Arduino as ISP sketch or similar
  3. parallel port of a computer
