In this second article on programming with Arduino you will see a fundamental element: the functions and the role they play. At the end of this lesson, you will be able to recognize a function within a sketch, and you will have all the necessary knowledge on how to define them and use them for your purposes and projects.
The WiFi101 library allows you to programmatically use WiFi technology on Arduino systems powered by Arduino WiFi Shield 101 or directly using the Arduino MKR1000 board that has integrated WiFi. Needless to say, this library is one of the key building blocks for the development and use of Arduino as a IoT solution.
On the big stage of the Arduino and Arduino-compatible electronic boards there is a new protagonist: Circuit Playground. This board is developed and distributed by Adafruit, and its name is very meaningful….this board is a “playground” for all makers.
In fact, it contains all the features of an Arduino LilyPad board, such as flexibility for wearable designs, but at the same time contains some electronic components (such as multicolored Led, buttons and light, sound and temperature sensors). With these components already integrated, you can create your projects and test them with only this board. Let’s look at it in more detail in this article.
In a previous article you’ve already seen how to integrate a generic LCD with Arduino. In this article you’ll see how to do the same thing with the LCD03 LCD. The power of this module is mainly the possibility of directly integrating a keypad. This option greatly expands the opportunities for viable projects of Arduino
During the building of your projects for Arduino, you’ll often need to read the output data directly from a LCD display. In this article you will see how to mount a LCD display on your Arduino using the I2C communication. Finally you will see how to program it with a simple example showing how to display text on the display
In this article you’ve seen how to integrate your projects on the Arduino with a WiFi system. Have you seen all the necessary tools to do so, as WiFi101 shield for Arduino boards, and the model Arduino MKR1000 (Genuino MKR1000) where WiFi is already integrated. Also you saw how to install and properly configure the firmware and WiFi101 library. In future articles you will see some useful examples on how to use it.
The world IoT (Internet of Things) is becoming increasingly popular in the world around us. We are still fascinated by this world of sensors and microprocessors that are increasingly interfacing more in our daily lives. If you are reading this article you probably know Arduino UNO and how it has revolutionized our lives, both as makers and as geeks of various kinds … Well Arduino has developed a new much more specialized board for IoT: the MKR1000
This is the second part of the article published about a week ago that concerned the PIR motion sensors, explaining the technical details on their usage and operation (see here). In this article, continuing with the topic, you will see how to use them in a more practical way, or better, by using an Arduino board (in my case an Arduino UNO).
