One problem with all those Arduino variants is, that the pins are different between them. Most of the example sketches are written for the Uno, which is the most common variant. And often the pin ...

7-segment-display's use 8 pins that connect to a microcomputer, in our case an Arduino. The display itself is divided in 2 main parts: A-G letters (marked with A,B,C ...

In this second article we will see a practical application of the daisy-chained shift registers. We want to use four 7-Segments LEDs controlled by the Arduino board. As you can imagine, that is ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

A Microcontroller uses many different protocols to communicate with various sensors and modules. There are many different types of communication protocols for wireless and wired communication, and the ...

The Arduino Development Platform, at the beginning in 2005, was conceived to be a simple programmable device to be used specifically for art design work. The goal was to create an interface to support ...

In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this setup as a pan-and-tilt controller for a laser pointer. The following is excerpted from the ...
