Attiny85 Audio Spectrum Analyzer on OLED display


https://www.electronics-lab.com/attiny85-audio-spectrum-analyzer-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 fed into it. The goal of this project […]

Webtronics’ Toasty USB Development Board Is Designed Around an STM32


https://www.electronics-lab.com/webtronics-toasty-usb-development-board-designed-around-stm32/

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 the competition with a new board named Toasty. Toasty is an […]

32 band audio visualizer using an ATTiny85


https://www.electronics-lab.com/32-band-audio-visualizer-using-attiny85/

“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 on ongoing personal project right now which I mean to […]

Tiny TFT Graphics Library for ATtiny84


https://www.electronics-lab.com/tiny-tft-graphics-library-attiny84/

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 is a new project by David Johnson-Davies. […]

ATtiny85 Thermocouple Thermometer measures up to +1350°C


https://www.electronics-lab.com/attiny85-thermocouple-thermometer-measures-1350c/

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 thermocouple voltage, and the internal temperature sensor to measure the ambient temperature (shown on the […]

Twelve PWM outputs from an ATtiny85


https://www.electronics-lab.com/twelve-pwm-outputs-attiny85/

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 rotating wave of light that moves […]

ATtiny85 Weather Station with SD1331 OLED display


https://www.electronics-lab.com/attiny85-weather-station-sd1331-oled-display/

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 96×64 SD1331 colour OLED display. by David Johnson-Davies: To display the readings the Weather Station uses a low-cost 96×64 OLED display with 64K colours, and an SPI interface. It’s […]

Widget Dashboard for ATtiny85


https://www.electronics-lab.com/widget-dashboard-attiny85/

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 96×64 SD1331 colour OLED display. by David Johnson-Davies: You can include any widgets from a selection of different types, and they automatically lay themselves out on the […]

Tiny MIDI Player using ATtiny85


https://www.electronics-lab.com/tiny-midi-player-using-attiny85/

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 simultaneously. My demonstration program plays the […]

Tiny Function Plotter using ATtiny85


https://www.electronics-lab.com/tiny-function-plotter-using-attiny85/

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 128×64 I2C OLED graphics display. Unlike most Arduino graphics libraries this routine doesn’t require a RAM buffer, and so will work on any processor down to an ATtiny85: The […]
