It shouldn’t be too difficult to transfer the circuits and explanations to the 4 series.Ī data sheet for this subfamily can be found here. In the further course of this post, I will primarily deal with the ATtinyx5 series. In contrast to the ATtinyx5 series, 12 I/O pins are available. The pinout schemes of the ATtiny84, 44 and 24 are also identical. Pins 1, 5, 6 and 7 alias PB5, PB0, PB1 and PB2 alias RESET, MOSI, MISO and SCK are used to upload the sketches.Ī data sheet for this subfamily can be found here. In addition to VCC and GND, there are six I/O pins that have multiple functions as you are used to from the Arduino. The pinout schemes of the ATtiny85, 45 and 25 are identical.

Pinout of ATtiny85 & Co Pinout of ATtiny85 / 45 / 25 This is a module based on the ATtiny85, which is programmed via USB. If you want it even easier, you can also use the Digispark as an alternative. This post is primarily about getting started and uploading sketches. Likewise, I will discuss the characteristics of the ATtinys and the differences to the big brother ATmega not here, but in another post. At a later date, I will come back to this as a separate topic. I will only briefly go into the latter method, as a step-by-step introduction would be too long for this post.

AVR Dragon or Atmel-ICE and Atmel Studio.

Arduino as programmer and the Arduino IDE.

In this post I want to show you how to upload your sketches to ATtiny85 & Co using the following devices: You should always check whether you can get along with the space- and energy-saving little brothers ATtiny85, 84, 45, 44, 25 or 24 (short: ATtiny85 & Co).

on the Arduino Nano or the Arduino Pro Mini board. Often there are projects for which you actionally don’t need the big ATmegas like the 328(P) or 168.
