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.
You value the project because you are able to customize and experience the process of its creation, both physically and mentally.
You have a Raspberry Pi, or are comfortable with the idea of using one, and you want to use it to capture video or images using a USB camera. Even though the Raspberry Pi has a port designed specifically for using a camera, it’s not as low-cost, nor as convenient as the USB corded camera.
Sound plays an important role in the user experience by adding another layer of depth; making for a more realistic experience.
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:
They are in games, decorations, shadow boxes, sign borders, torches, spotlights, and so on…
