ARDUINO RIG DOES SPECTROPHOTOMETRY

Spectrophotometry is an important scientific tool, most commonly used in biology and chemistry. It’s a method to measure the amount of light absorbed by a chemical solution at various different wavelengths. While it’s typically the preserve of expensive lab equipment, [Daniel Hingston] built a rig to do the job at home. The heart of the rig is a normal filament-based flashlight bulb, which produces good-qua ...

Berry Racer – a Game Programmed in Arduino and Played on a Custom PCB

https://youtu.be/C8IPaMl1wTk Berry Racer is a game that I came up with and programmed using Arduino's Software. The game is run on a Teensy microcontroller which is connected through a custom PCB (Printed Circuit Board) to a Screen, a Joystick, four buttons, and a piezo speaker. The board can be powered through the micro USB port on the Teensy or with a battery that can be plugged into the back of the PCB, ...

Imitation Fireplace Using Cool Mist and LEDs

Build a convincing artificial fire effect for the holiday season using NeoPixel LEDs, an Arduino UNO, and a cool mist module. Story This is a project I've had on the backburner for almost exactly 1 calendar year. The seed was planted when I toured the Harry Potter Studios last year and saw a fake fireplace effect being used quite extensively. I am also an avid watcher of the "Fireplace for your Home" Netfli ...

RoboBee – A Flying Microbot That Can Perform Search And Rescue Missions

Inspired by the biology of a bee, researchers at the Wyss Institute developed RoboBees, man-made microbots that could perform endless roles in agriculture or disaster relief. A RoboBee is about half the size of a paper clip, weighs less than one-tenth of a gram, and flies using materials that contract when an electric pulse is applied. Now, they progressed even further and designed a hybrid RoboBee that can ...

New Arduino Book Teaches Electronics Skills One Project at a Time

The Arduino microcontroller makes it easy to learn about electronics, but it can be hard to know where to start. The 10 projects in this book will teach you to build, code, and invent with the super-smart Arduino and a handful of parts. First, you’ll master the basics with a primer that explains how a circuit works, how to read a wiring schematic, and how to build and test projects with a solderless breadbo ...

How to measure temperature very accurately with an Arduino

While studying in university we were challenged as part of a course work into designing a box with very accurate temperature control. If the project were to succeed, multiple boxes were to be built and used in a research project studying the effect of surface material on the perceived temperature of flooring and other building materials. The project was deemed as very challenging by the university staff bec ...
