SlouchyBoard - an Annoying Way to Keep You From Slouching (Intro to EasyEDA)

“Slouchy board is a small 30mm x 30mm PCB (Printed Circuit Board) that uses a tilt sensor, a piezo buzzer and an ATTiny 85 to make an annoying sound when the user is slouching. The board could be attached to …

Vibrating Watch to Remind Wearer Not to Waste Time

“Everyone knows that time is both fleeting and limited. And yet we still forget this simple truth and continue to waste time on unimportant things. I created a watch that would vibrate every 5 minutes to constantly remind me to …

Working RC Car Speedometer

“This is a short project that I created as part of a larger RC build of a Lightweight Land Rover. I decided that I fancied having a working speedometer in the dashboard, but I knew that a servo wouldn’t …

a tiny software UART TX for the AVR ATtiny

“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 …

Tiny Thermocouple Thermometer

“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 …

How to Setup DigiSprak Attiny85 Board

“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 …

Neopixel LED Heart

“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 …

Twelve PWM outputs from an 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 Each LED can be set to a brightness between 0 (off) and 63 …

Individually Addressable LED Hula Hoop

“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 …

ATtiny LED Matrix Display Badge

“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 …
