In your Arduino journey so far, you’ve likely most often used the microchip ATmega328P-PU. For smaller projects, however, you can save money and power by using smaller microcontrollers such as the ATtiny85. In this chapter, you’ll learn how to configure the Arduino IDE for ATtiny microchips.
After setting up the Arduino IDE for your ATtiny85 and flashing an LED to demonstrate that the toolchain is working, you’ll learn to:
Understand the ATtiny pin references for the Arduino environment and the functions available for ATtiny use
Add a reset button to ATtiny circuits
Use port manipulation with ATtiny
