Power Analysis: Probing WS2812 RGB LEDs
Power analysis is a technique to probe the inner workings of an integrated circuit by measuring changes in the supply current. Tim writes: Whenever a logic gate switches, it will cause a tiny current spike that can be measured externally. By inspecting the temporal variation,...

ESP8266 temperature logger
A ESP8266 temperature logger project from Facelesstech: I decided to use the esp-01 module because I only need 2 GPIO pins since I was using the DS18B20 temp sensor and the WS2812 LED. This made the hardware really cheap and easy to reproduce too. I normally use FTDI boards when it...

8×8 RGB Led Matrix with WS2812 driver with Arduino Uno
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...
