The relatively inexpensive system known as the spectral transmission-reflectance-intensity (TRI)-Analyzer costs only $550. The device uses light and spectral analyses to do many of the most common laboratory tests.
Given the device’s capabilities, it is able to adapt to perform a wide variety of tests without the need for a dedicated laboratory. Any test that utilizes a liquid that changes color or generates a light output (think fluorescent dyes) can be run on this device hooked up to a smartphone.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
