An automated hydroponic system #PiDay #RaspberryPi @Raspberry_Pi
Hydroponic farming is a method of growing crops without soil, with the main benefits of environmental and nutrient control, water conservation, and reduction of labor. This technique relies on a number of technologies that the principles of automation can be applied in order to improve yield and consistency.
At the core of this automated hydroponic system is the Raspberry Pi single board computer. This $35 computer is only the size of a deck of playing cards, but it has all the components you would find in a full computer, including CPU, RAM, video/audio output, USB, WiFi, Bluetooth, Ethernet, and micro SD slot.
The most important feature of the Raspberry Pi for our application is its general purpose input-output (GPIO) pins, which will be used to connect inputs, such as switches and sensors to measure the environment, and outputs such as pumps and relays to move liquids and control electrical devices that will manipulate the environment.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
