How to install the librarie of Attiny

To start programming a PCB with Arduino you have to install its library and to do this, we must open the "Preferences" option and add the library in "Additional boards manager URLs"
NOTE: I had a problem with the link that my instructors shared with me, because it marked an error when trying to upload the code to the microcontroller, so we looked for a different one on the internet.

And since an Attiny requires another microcontroller to be programmed, I used an ARDUINO UNO as a programmer, but it must be configured for this purpose.

ARDUINO as ISP

For an Arduino to work as a microcontroller we must select the "Examples" option and click on the "ArduinoISP" option.
We connect the Arduino to the Computer and in the "Tools" option we select "AVR ISP" and we proceed to load the code into the ARDUINO

Attiny configuration

To program the Attiny, we must first "burn Bootloader" and to do this you must connect the Attiny to the Arduino with Jumpers and Change the state of the Arduino from "AVR ISP" to "Arduino as ISP"
