After the FTDI gate it's time for the Prolific gate, another USB to TTL chip driver issue puts plenty of devices at risk of being trashed. Luckily the solution is pretty simple and well documented on this site.
Following the enthusiasm of my previous post, I wish to share an interview a good friend of mine gave to me the latest days of August for his own blog. The original interview run in Italian, but here I'm posting an English translation: thank you Francesco for pushing me into learning Arduino! Zeirus: Hi Roberto. … Continue reading FlexiPower: the interview
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 … Continue reading Am I a Meta Maker™?
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 … Continue reading Programming an ATmega328
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 … Continue reading USBasp & Windows 10
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 … Continue reading Win 10 FTDIgate solved!
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 … Continue reading nRF24 walk through – Introduction
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 … Continue reading nRF24 walk through – Building the sensors
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 … Continue reading nRF24 walk through – Sensors’ firmware
