simone @ loquentarduino.github.io writes: When I first run a Machine learning project on my Arduino Nano (old generation), it already felt a big achievement. I mean, that board has only 32 Kb of program space and 2 Kb of RAM and you can buy a chinese clone for around 2.50 $. It...

tinyPulsePPG, an ATTiny85 Pulse Oximeter with Photoplethysmogram (PPG) display by Jeff Magee: This project implemented on an ATTiny85 displays a moving Photoplethysmogram together with pulse rate and estimates of SpO2 – blood oxygen percentage. It uses an SSD1306 128×32 OLED display...

Visualizations are an important part of a music player. They provide the user with something to feast their eyes on especially when the music has no video. For today’s tutorial, we will build a visualization device, capable of providing a visual representation for any kind of music...

There are quite a number of USB development boards available that can be utilized for any number of projects, with the most popular being the ATtiny85 and the Teensy line from PJRC. However, UK-based Webtronics have recently announced their entrant into the USB development board into...

"attiny85-spectrum" is a 32 band audio visualizer using an ATTiny85 and an SSD1306 OLED display. Built in Arduino. The goal of this project is to get smooth, appealing music visualization on the ATTiny85, optimizing around its limited speed and resources (RAM and program memory). Its...

This is a graphics library for the family of small colour TFT displays based on the ST7735 and ST7789 driver chips. These are really nice displays; bright, colourful, available in a variety of useful sizes, and available at low cost from suppliers like Adafruit, AliExpress, or Banggood....

This project describes a thermocouple thermometer, capable of measuring temperatures up to +1350°C, using just an ATtiny85 and an OLED display. by David Johnson-Davies @ technoblogy.com It uses the ATtiny85's analogue-to-digital converter with a x20 gain option to measure the...

This project describes how to get 12 analogue PWM outputs from an ATtiny85, so you can drive 12 LEDs with individual control over each LED's brightness. David Johnson-Davies writes: Each LED can be set to a brightness between 0 (off) and 63 (fully on). The demonstration program shows a...
