The coders corner has a (fairly active) account on github. From Arduino libraries, Joomla to Hugo through to examples for the datacomms section, why not take a look.
Over the past month or two, I’ve finally fixed up some snags that I had when building the honey badger amplifier. When I first built it, I had a difficult time trying to track down dry joint on one of the start boards - it also had a bad IDC connector delivering power to it. In addition the PSU boards had a fault and needed to be stripped down and moved to new boards.
In this tutorial, I present a fictional SPI chip that we will use for the sake of example. This chip has two LED’s and controls them over SPI. It will help us to understand SPI with a real worked example. Following on we will build a real world circuit, using the SPI library, to see how easy it is to use SPI on Arduino. Serial Peripheral Interface (SPI) Introduction Serial communication allows less pins to be used to communicate information between two chips or boards, and also removes a whole class of timing issues that are associated with parallel communication.
If you run you hosting on a Linux server, it normally comes out of the box pretty secure with few of the older less secure services enabled. On top of this, if you use a provider like AWS they further secure the server by their own custom firewall. I truly like Amazon Web Service and have used it for some time. They can scale from mom-and-pop shop right up to enterprise.
