This is a weather station based on an ATtiny85 and an Adafruit Bosch BME280 sensor breakout. It displays the atmospheric temperature, pressure, and humidity on a 96x64 SD1331 colour OLED display. by David Johnson-Davies: To display the readings the Weather Station uses a low-cost 96x64...

This project is a dashboard for displaying the outputs from up to four different sensors or Internet of Things devices. It's based on an ATtiny85 driving an SPI 96x64 SD1331 colour OLED display. by David Johnson-Davies: You can include any widgets from a selection of different types,...

David Johnson-Davies published another tiny project. This is an ATtiny85-based digital music box that will play a tune stored in memory in MIDI format: The notes sound like a music box or harpsichord, with a decaying envelope, and there are four channels, so up to four notes can play...

David Johnson-Davies build a OLED display function plotter based on ATtiny85 microcontroller. He writes: This project describes a simple routine for plotting a function on a 128x64 I2C OLED graphics display. Unlike most Arduino graphics libraries this routine doesn't require a RAM...

Here is a new tutorial from technoblogy.com on how to run ATtiny85 with internal 20MHz clock. The ATtiny85 is rated at a maximum clock speed of 20MHz at 4.5 – 5.5V. For some applications it would be nice to get the maximum speed without needing to buy a 20MHz crystal, or tie up two...

David Johnson-Davies published another great project. It's an IR remote that supports the most popular control protocols. The IR Remote Wand is a universal remote control that you can program with up to five codes to control a variety of different products: It supports some of the...

David Johnson-Davies published another great and detailed tutorial on how to build an IR remote control detective. He writes: The IR Remote Control Detective decodes the signal from several common types of infrared remote control, such as audio, TV, and hobbyist remote controls. To use...

David Johnson-Davies published another great and detailed project based on ATtiny85. It's an harmonic function generator with an OLED display. This article describes a simple function generator based on an ATtiny85 which allows you to generate a virtually unlimited number of waveforms...
