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.

It does all the things he needs, but now and again he would like to use something a bit smaller, without all the bells and whistles the Arduino has to offer. He contemplated using an ATtiny for ...

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 ...

I also need to get my ATtiny to go to sleep when not processing anything. And that involves setting pins to ‘interrupt-on-change’ and getting the chip to ‘wake-on-interrupt’ – all stuff I could have ...

Having had such quick success making a microcontroller project using an 8pin ATtiny85 and ... so one more pin it is. It transpires that folk have been busy writing ‘cores’ – the name for code that ...

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 ...
