Microscopes are common pieces of equipment in laboratories (or even high school science classes for that matter), but making movies of living cells usually requires more expensive and specialized tools… until now. With a 3D-printed mount for a smartphone and an Arduino, researchers at Sweden’s Uppsala University have been able to retrofit ordinary microscopes to take time-lapse sequences.
To accomplish this, an Arduino was used to control a shutter for the smartphone to minimize light exposure when capturing intermittent images, while a heating unit was employed to maintain a constant temperature for the tiny organisms.
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.
