“The serial port is a very commonly used interface for communicating between a microcontroller and a PC for debugging or sending or receiving some values. Most microcontrollers include a hardware peripheral called UART (Universal Asynchroneous Receiver Transmitter) which handles the …

“This project describes a thermocouple thermometer, capable of measuring temperatures up to +1350°C, using just an ATtiny85 and an OLED display. It uses the ATtiny85’s analogue-to-digital converter with a x20 gain option to measure the thermocouple voltage, and …

“Hello there Engineers and Hobbyists, we all love Arduino’s right! But using an Arduino UNO, NANO or any other Arduino for a small task like displaying a simple message on LCD or just Fading LED would be waste of …

“Neopixels are color-changing, individually addressable (programmable) LED lights. They are available in various forms from Adafruit.com, but I am particularly fond of the 8-mm “through the hole” traditional LED style. They are bright and beautiful, and you can make …

“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 Each LED can be set to a brightness between 0 (off) and 63 …

“In this instructable I am going to show you how to make your own individually addressable LED hula hoop. Individually addressable means that each LED in the hoop can have a different color at the same time. I wanted to …

“An ATtiny85-based badge-size PCB that can display letters and numbers. Have you ever thought of making a badge-sized PCB that can display some letters, numbers, etc… or your name? In this project, I will be showing how I built a …

“It’s a Stargate PCB for your desktop—engage those chevrons and establish a wormhole! Stargate SG-1 is my favorite TV show of all time—full stop. Over the past couple of months, I’ve been forcing my girlfriend …

“This is a PCB version of my earlier Tiny Function Generator project based on an ATtiny85. It uses Direct Digital Synthesis to generate sine, triangle, sawtooth, square, and rectangular waves, a pulse train, and noise. The frequency can be adjusted …

“In this Instructable I show how I my a Christmas star using neopixels, driven by a Attigny digispark board, mounted on a 3D printed star”
