LilyPad Arduino is one of the many Arduino microcontrollers, but unlike the more well-known Arduino UNO, MEGA and Yun, this little board has very specific characteristics that make it unique. In fact, the LilyPad can be sewn on fabric. In fact, with less than 5€ you can add technology to our garments, but also bags, shoes, diaries, and so on. In this article we will know in detail this board and we’ll see some examples of how it has been applied in some exciting projects.
This component (a small chip) HMC5883L, produced by Honeywell, bases its operation on AMR (Anisotropic Magnetoresistive) technology and allows you to be able to measure both the direction and the magnitude of the earth’s magnetic field. This magnetometer HMC5883L has within 3 magneto-resistive sensors arranged on three perpendicular axes (the Cartesian axes x, y and z).
So far most of us have always believed that Raspberry Pi and Arduino as two competing platforms. Not by chance among various geeks and maker is not uncommon to show a bit of competition for Arduino fans against the Raspberry Pi fans. Well today I will slightly change things, and show you how you can take advantage of the best of everything. If you own both Arduino and Raspberry boards, this article will show you how to best and synergistically make use of these two boards.
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).
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
