Arduino illuminated sign

Nowadays led signs and banners are getting more and more popular, also their price is going down slowly, but personalized ones still have a spicy price, so I`ve decided to make one by myself for less than 30$.

I wanted to lit up every character separate in order to make it look more interesting and professional, so I had to use a cheap and small Arduino Nano board.

Using a six wire stepper with an Arduino Uno and Adafruit V1 Motor Shield

In this article I am going to present the basics about using a stepper motor with an Arduino Uno and an Adafruit clone stepper shield.

There are many kind of stepper motors around. From small ones that can be found in digital cameras to bigger ones that can move huge CNC machines back and forth. They usually come with 4, 6 or 8 wires, but they can have even more wires, and special techniques to rotate.

Getting started with Arduino programming – Installing the IDE(s)

How to enter the Arduino word? Before anything else we have to setup an environment where we do the coding. There are many options you can choose, about how you want to code the boards. In this post I am going to speak about two specific ways.

A microcontroller is basically a one chip computer, every component a computer needs to have in a single integrated circuit. It contains a processor core, memory, and many programmable IO (input and output) ports. They are used in embedded projects and mostly in automatically controlled devices like tools, automobiles, medical devices, remote controls, toys, microwaves, washing machine and so on. Basically we are surrounded with them almost everywhere. Continue reading What are Arduino microcontrollers?
