Electricity replaces the sun, wind, and some natural processes as the dependency for plants to grow indoors.
The first glaring problem with the typical indoor garden is that extension wires are annoying and a potential safety hazard. On the other hand, wireless communications can lack the reliability of the wired variant. Going further, should the system be available to the local network or should it be connected to the Internet?
The greatest advantage to using the Arduino family of microcontrollers for DIY electronics projects, is that they are ubiquitous. Since they are so available, they are inexpensive and you can find open-source software to get started.
If you’ve ever had the opportunity to work with an Arduino Uno microcontroller board, then you’ve probably executed the flashing LED example. Going further, you might attach a button, or switch, to trigger the LED or to turn it off making the project interactive. There are many sensors that could be connected to the Arduino Uno and setup to trigger events, such as the LED flashing, using threshold values that we would need to experiment with in order to figure out what settings work best for creating the effect we want.
Using an Arduino Uno to calibrate an RGB LED strip.
The purpose of running this example is to determine what settings are needed to use the FastLED library. For this example I’m using an Arduino Uno. The Uno has a ground pin next to pin 13, so for convenience, I’m using pin 13 as a low-current Vcc for the RGB LED lights strip:
In my previous article , I explain how to setup the Raspberry Pi to be a web server. I also demonstrate searching log files for “footprints” from the IP requests that have been made to your web server. Now, I would like to discuss protecting your web server from becoming a victim to a potentially malicious attack.
