The HD44780 is a controller for display developed by Hitachi commonly used to manage alphanumeric dot matrix LCD. This controller is a standard de-facto for this kind of display. It is often used in industrial test equipment, networking equipment, vending machine and in embedded ...
The DHT11 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed).
The communication on data pin occurs according to a ...
When I started with embedded my knowledge about programming was (and probably still is) very elementary. I often used logical operator like logical NOT (!), logical OR (| |) and logical AND (&&) but was almost ignoring the bitwise operators.

By this article, we will show schematic of ChibiCube in order to understand how it works and hot it has been designed.
As mentioned in the previous article, ChibiCube addresses all its LEDs through the combination of anode and cathode signals. Each floor of the cube is configured as common ...
ChibiCube is a 3D LED matrix 8x8x8 composed by monochromatic LEDs individually addressable: that means not only every single LED could be in a ON or OFF state but everyone could be set at different light intensity.
In December 2012, students Ciro Domenico Pagano from University of Salerno, ...
