DIY project usually is prototyped using breadboard. Big mess of wires, and some chips between :) It is very convenient build it that way. Rewire connections? No problem, just switch some wires. However, when project is done and You want to use this prototype in the filed, it turns out, what was advantage has suddenly […]
Sometimes, when Arduino IDE wants You to fix some code, and You have no idea why it is complaining, maybe it’s IDE and not You? :) See this error, at first glance – WTF? This is very specific case, and can make You scratch head for several minutes. But true is very simple.
Arduino YUN is very powerful tool especially with data acquisition services like ThingSpeak. Today we had urgent need to get some data from sensors, and running simple sketch and making data available through ThingSpeak was a breeze:
Arduino YUN is very interesting product. Mixing OpenWRT and Arduino in one board is effective. OpenWRT does things related to WiFi connectivity, Arduino YUN does interact with physical world, and standard Arduino library makes connecting both parts easy. Now we need some simple project to demonstrate how You can control things remotely with Arduino YUN […]
Let’s start with short movie. Yet another blinking example, but this time, can You spot something unusual for such example?
In the previous post we’ve finished with reading files from SD card. Now we have to pass them through our PHP :) and send the results to the client. To make whole process more simple, we’re assuming each of the files is known to us. This means, we’re registering every file (URL) with addCommand. How […]
If you already know Arduino stuff a bit, maybe you want to connect it with a network somehow. It could be some network-enabled home automation solution or a set of sensors sending data to a database. So, here comes the Ethernet Shield to help you. First, a bit of history. Initially, the Ethernet Shield was […]
Everyone, who has been making a project based on Arduino probably wanted the board to be smaller than the basic unit. A variety of smaller, but compatible with Arduino, boards have been developed. One of them is SparkFun’s Arduino Pro Mini. Currently, it has ATmega328 onboard and its dimensions are 33 mm x 18 mm. […]
The following article is based on this entry on Newton’s blog (in Polish). All the pictures, program code and the video clip came from there. This project’s goal was to use as many parts from the Arduino Starter Kit, as possible. So, what is this project exactly? As the title itself suggests, it’s a game, […]
Switches (buttons, pushbuttons, tact switches) are commonly used with Arduino. But, for beginners, it’s sometimes irritating when it comes to wire them up correctly. Some of their terminals are shorted with each other. Such a switch doesn’t work if putted in reversely. Because of that, here’s some words of explanation. For instance, we have a […]
