“This relatively easy tutorial (considering the complexity of this subject matter) will show you how you can make a very simple 1024 samples spectrum analyser using an Arduino type board (1284 Narrow) and the serial plotter. Any kind of Arduino …
“Columbia researchers first to discover a quantum fluid—fractional quantum Hall states, one of the most delicate phases of matter—in a monolayer 2D semiconductor; finding could provide a unique test platform for future applications in quantum computing Columbia University …
“3D printed robot arm running on Arduino, contributed and supported by an active community. This 3D printed robot arm featured in 20sffactory is largely based on the popular design by Florin Tobler shared on Thingiverse. His open source design kicks …
“I have previously done an 8x16x8 Led Cube Clock controlled by Arduino Mega 2560 and Real Time Clock Module DS3231 more than 2 years ago and until now it still works fine. I also conducted the tests using ESP-01 …
“Scientists have recently engineered a modular system based on the Rubik’s cube to design and reconfigure microfluidic systems. Research teams had previously pursued the arrangement of microfluidic blocks in diverse conformations to suit varied experiments. In this work, Xiaochen …
“Display quotes and synthesize speech on an Adafruit PyPortal using CircuitPython and AWS Serverless. As a natural means of communication, voice is a powerful way to humanize an experience. What if you could make anything talk? This guide walks through …
