In this video we learn how to use this 8x8 RGB LED matrix. This matrix is using the WS2812 driver and it is great, because each LED is individually addressable. Only one microcontroller pin is required to control all the LEDs, and you get 24 bit color for each LED. 8x8 RGB Led...

Dan Watson has designed a tiny breakout board for the Atmel ATtiny10. The board includes a bypass capacitor, a power LED and a user LED: This breakout board is for the ATtiny10 microcontroller. The PCB is 0.25×0.325″ and uses 0.050″ header pins. The board could actually be made...

Danny Mavromatis has designed an Arduino based OBD port module using Atmel 328P MCU and Microchip MCP2515 CAN Bus controller with SPI interface and MCP2551 CAN transceiver. The goal of this project it to create an Arduino based OBD port module that can be used to enhance a vehicles...

Vlad @ denialmedia.ca has build a solar powered weather station based on ATMega328 microcontroller that is able to measure temperature, a humidity, and UV radiation and it uploads measurement on WeatherUnderground network. The data are send to the air using a 433MHz link. The...

This is a great ATtiny85 watch that uses a SSD1306 OLED display and is powered by a CR1220 battery. Today core subject, ATtiny85. Someone suggest me to use SOIC version to reduce the watch size and I found the coin cell mAh calculation method will count the battery voltage down to...

The Minibot is a small autonomous robot vehicle that uses phototransistor that can detect lightness patterns on the ground to follow the edges of the dark lines. It has a MC9RS08KB4 MCU, coin cell, motor, and a phototransistor. The MC9RS08KB4 is part of the MC9RS08KB12 series, a...

MindForge @ 43oh.com build a datalogger board which logs accelerometer values on a SD Card. The datalogger is built around an MSP430G2755 microcontroller and ADXL335 accelerometer sensor from Analog Devices. his project started as an EMG datalogger to study my dad’s Parkinson’s...
