Start by installing the Arduino IDE https://www.arduino.cc/en/software
Open the preferences OR settings dialog in the Arduino software menu.
Find the “Additional Boards Manager URLs” field near the bottom of the dialog.Paste the following URL into the field (use a comma to separate it from any URLs you’ve already added):
then press OK
From the Arduino IDE menu, go to Tools > Board > Boards Manager
In the boards manager on the left search for and install ATtiny
Plug your ATtiny controller to the programmer.
Plug the programmer to your computer. Use an adaptor if you need to.
Back in the Arduino software, choose your board
ATtiny25/25/85
Choose your Processor ATtiny85
Choose your clock (processor speed). You can choose any internal clock but the faster the clock the quicker your battery will drain. I recommend Internal 1mhz for most projects.
Under tools, Choose your programmer which is
USBtinyISP
In the code window, paste this code and see if the programmer's built-in yellow LED flashes. If so, you're ready to work on your own code.
Once you have the code, you need to transfer the ATtiny to a circuit or a breadboard to test.
