David Johnson-Davies published another great tutorial on how to use the Tiny Graphics Library to plot the outside temperature over 24 hours on a 128x64 OLED display using an ATtiny85. This small graphics library provides point, line, and character plotting commands for use with an I2C...

David Johnson-Davies build a tiny function generator based on ATtiny85 microcontroller. He writes: This article describes a simple function generator based on an ATtiny85. It can generate triangle, sawtooth, square, and rectangular waves, a pulse train, and noise. The frequency can be...

What is the lowest possible clock frequency at which a microcontroller can still do useful work? Here’s a little project that attempts to explore this weird question. by igendel @ idogendel.com: ATtiny85 runs at 0.000011574Hz clock -...

This article describes a simple continuity tester based on an ATtiny85. The tester features a buzzer that sounds to help you determinate the trace continuity. It is designed for checking circuit wiring, or tracing out the tracks on a PCB. According to it's author David Johnson-Davies it...

The BeanDuino is an ATtiny85 based microcontroller development board similar to the Arduino line highly inspired by DigiSpark , BeanDuino is hardware compatible with Adafruit Trinket / Gemma. Specifications: Support for the Arduino IDE 1.0 and later (OS X, Windows, and Linux)...

Chris @ chris3d.com build his own Attiny85 board:  The modularity of Arduinos is great, but after playing with them for a year or so, I wanted to start building things that needed a little more integration. I also wanted to design the components and programming around the actual...

An ATtiny85 and a 64x48 OLED display hand clock: This is the third in my series of minimalist watches based on the ATtiny85. This version displays the time by drawing an analogue watch face on a miniature 64x48 OLED display. It uses a separate crystal-controlled low-power RTC chip to...

This is a simple fan controller with single LED temperature status light using an ATtiny85 microcontroller and DS18B20 temperature sensor. The fan is turned on/off based on temperature sensed and the controller goes in sleep mode when the temperature drop below a predefined...
