What is Arduino®
Arduino® is an open-source prototyping platform based on easy-to-use hardware
and software.
Arduino® boards are able to read inputs – light-on sensor, a finger on a
button, or a Twitter message – and turn it into an output – activating a
motor, turning on an LED, publishing something online. You can tell your board
what to do by sending a set of instructions to the microcontroller on the
board. To do so, you use the Arduino programming language (based on Wiring)
and the Arduino® software IDE (based on Processing). Additional
shields/modules/components are required for reading a Twitter message or
publishing online. Surf to www.arduino.cc for more
information
Product overview
Use this sensitive measurement board to determine the quality of water-based
on its total dissolved solids or TDS. Find out whether your tap water is
clean, or keep an eye on your aquarium water, and more!
