Step 1: Instaling the Library

In preferences of arduino software set the following "json" in the URLs option and press "ok"

In the boards manager search "attiny" and instal the option of the picture 2

Step 2: Configuring Arduino Software

Following the configuration of the options in "Tools" and , we can use and program the attiny with an Arduino hardware as a programmer.

Step 3: Burning Bootloader of Attiny

To be able of use the microchip, we need to follow the picture and set the option "burn bootloader" in "Tools" of the software.

The conections of the image are important beacuse these are necesary to upload the code to the attiny, to use the attiny with the code only needs power.
