Yesterday has been a special day for me. It started as any other day of my recent life, with a late alarm after a too short sleep. As usual I had my morning shower and rushed into the office were I spent my day working together with the other members of my team and running […]
Everyone, when they’re starting out on the Arduino and similar boards, learns to use the String object for working with text. Or they think they do. Well, you should forget all you think you know about strings … Source: The Evils of Arduino Strings
Ever heard about Barebone Arduino? It consists of trimming down an Arduino to it’s very basic parts and can be really effective in cost reduction. Even it might seem the simplest version of an Arduino (actually I wouldn’t be calling it an Arduino any more) we can go even further and drop the external crystal in […]
If you have an USBasp programmer and a recent Windows machine you have more than probably stumbled into a disappointing message, either from Arduino IDE or Sloeber: avrdude: error: could not find USB device with vid=0x16c0 pid=0x5dc vendor=’www.fischl.de’ product=’USBasp’ I believe I’ve spent at least a couple of hours searching for a solution which would not […]
In the office we have recently decide to migrate our team wiki to WordPress and Yada Wiki has been selected. The team is also quite comfortable with Markdown, even if not everybody is ready to adopt it as the main editor, so I struggled a bit to find a solution, until I stumbled upon Jetpack. […]
My recent upgrade to Windows 10 has brought back to me an old issue: FTDI drivers. Yes, I’ve bought cheap Chinese Arduino clones, mostly small boards to use in my projects as the official ones are quite expensive. I never had problems on my previous Windows 7 install: even if I knew I was probably […]
I have been repeating this statement over and over on the Cucumber forum, but apparently with no good result. To me this is a simple statement and I fail to understand what’s difficult to understand in its simplicity: Cucumber (JVM, Ruby, C, the flavour doesn’t matter) is not a testing framework. I’ll try to further explain […]
Let’s move to the 3rd part of the nRF24 walk through series before the excitement cools off, shall we? Now that I have three boards wired and I’m certain only my code can break things up, it is time to create the sensors’ firmware. It should be quite simple: all we need to do is getting the […]
It’s now time to physically build the sensor devices part of the nRF24 sensor network we are planning to build, so move to your electronics bench and pick some breadboards! From an electronics point of view each sensor node consists of: 1 Arduino (any low-end model will do, I will be using two nano and one pro […]
The Nordic nRF24 is a family of silicon integrated radio transceivers operating in the 2.4GHz band, the most popular one being the nRF24L01. This is the core element of some extremely cheap module boards available in online stores like eBay, Aliexpress and Banggood. These boards do not provide WiFi (801.11) or Bluetooth connectivity (both in […]
