Embedded Files
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
Here's some example code.
Paste this code into the Arduino code/sketch window.
Use the upload button in the upper left of the window to compile and upload the code.
If the programmer's built-in yellow LED flashes, you're ready to work on your own code.
Keep in mind that the ATtiny programming board only has one built-in LED, and it's on pin 0. If you need to test other pins, you'll have to program the ATtiny and then move it to your circuit board to see the results.
Next Challenge: How do you blink more than one LED?
