Literally, ATtiny85 is a scaled-down version of the Atmega microcontroller on Arduino boards with just a few I/Os (five usable pins) that can listen to or talk to most sensors and transducers.

[Ralph] wasn’t satisfied with the required 5 control pins to drive his nrf24l01+ transceiver module, so he used this circuit needing just 3 pin using an ATtiny85. One of the key components was ...

Planning another Arduino build? If you’re just doing something simple like switching a relay or powering a LED, you might want to think about the Digispark. It’s a very small ATtiny-based ...

ADC on 4 Pins. – Power LED and Test/Status LED (on Pin0). – Size: 1.8cm x 2.6cm If you ever tried to get started with Arduino or the miniature ATTiny85 chip, you have found there is a learning ...

Having had such quick success making a microcontroller project using an 8pin ATtiny85 and programming ... name for code that adapts Arduino code to run on different hardware – for several other bare ...

The ATtiny85 based mini development board is similar to the Arduino, but cheaper and smaller (ofcourse a ... this USB interface or from a suitable external source through the 3-pin connector J2 ...

set to flash the led that is soldered to Arduino pin 4 (actual ATtiny pin 3). The croc clip lead goes from the reset pin on the ATtiny (package pin 1) to Arduino Micro pin D10 when the Micro is ...

If you enjoy tinkering and building Arduino projects and gizmos ... Powered by the ATtiny85 with 3 available I/O pins, one of which is also an analog input and two which can do PWM output The ...

The Uno also has a limited number of pins, making it difficult to work with when the project requires plenty of input and output components. However, these two areas are where the Arduino Mega shines.
