“To examine how much “calculator power” a simple microcontroller like the ATTINY85 is able to perform was already the intention of ScArY (www.github.com/zooxo/scary). Unfortunately ScArY was based on a premanufactured development board (QYF-TM1638) and was …

“Shopping for family is a struggle for me around Christmas. I’m not the best at presents to begin with let alone finding something interesting they don’t already have. So, this year I decided to make my presents. This …

“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 …

“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 …

“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 …

“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 …
