Android and Bluetooth (1)
I’m currently working on a project that will be controller using an Android app; I thought it was time to write a tutorial about developing apps with bluetooth functionalities…
Yún – Sketch Uploader
One of the most useful features of Arduino Yun is the ability to upload your sketches via network, directly from the IDE (as I explained in a previous tutorial). Arduino’s IDE uses the Bonjour protocol (running on port UDP 5353) to look for Yun boards on your network: this auto-discovery technique works fine in a local area…
Yún – Factory reset for Linino
As you already know, Arduino Yun runs a Linux distribution named Linino. Sometimes you may need to perform a factory reset of that distribution, i.e. restore the original image shipped with the board. Procedure Download the image from Arduino’s web site: The image is zipped, unzip the content (a binary file with .BIN extension) on…
My3dP: first movements!
This weekend I spent some time to complete the setup of my 3d printer. First I replaced the extruder – I broke it during the assembly – with a new one from MakerFarm: After the fine positioning of the endstop microswitches, I could make the printer move!
App Inventor v2
The M.I.T. (Massachusetts Institute of Technology) has recently published the version 2 of App Inventor, a tool to develop Android apps. Its official website is http://appinventor.mit.edu/ App Inventor makes easy to develop – with graphical tools – both the GUI and the logic of a mobile app. I really appreciated how fast is to develop even complex applications connecting…
enc28J60 and Arduino (17)
In some of the previous tutorials, you’re already learned how to program simple sketches to remotely control leds, relays… today I’m going to show you how to secure those projects with the addition of a password.
Eagle – Pin names
Today, working on a new library component for Eagle, I noticed that both the pin name (configured in the component’s symbol) and the pad name (configured in the package) were displayed: When you add a new pin in the symbol editor, you can choose which name will be displayed (none, pad name, pin name, both)…
Playing with a led strip… (2)
After having introduced you, in a previous post, the led strips and after having explained how to control a digital strip, today’s post is about a simple project I made after a request from a friend: make a strip led blink at a variable frequency.
Olimex will move to KiCad for its new OSHW boards
In a post some days ago, Olimex announced they will move to KiCad for their new boards that follow the OSHW principles (OpenSource HardWare). As many designers and hobbists, at the moment Olimex uses Eagle as their preferred EDA tool. The post summarize the main limits in Eagles’s licensing policies and why they chose KiCad among the other available…
enc28J60 and Arduino (16)
After some months without posts, I’m going to continue this tutorial with some new projects… but first today I’d like to talk about a different library…
