Arduino DS18B20 Thermometer on iOS or Android
maroelawerner @ instructables.com has a tutorial on how to display temperature data on an Android or iOS device using Arduino and Blynk app. In this Instructable I am going to attempt to show you how to put together a little project to use the Blynk app (optainable at...

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...
