1. TRYING TO MEASURE THE SPEED OF LIGHT WITH AN ARDUINO We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. Last month we saw [Udo]’s blinkenlight shield that can be used as a line scan camera. It’s a neat piece of kit, but [Udo] really wants to […]
To blink an LED with an Arduino using Python, you will need to: Connect the LED to the Arduino board. You will need to connect the positive leg of the LED (the longer leg) to a digital output pin and the negative leg (the shorter leg) to a ground pin. Install the PySerial library, which
Meet Chartreuse! Chartreuse’s face follows you when you walk by. When she sees you, her eyes turn yellow and she gets a happy expression in her eyes. As you walk away, her eyes change to blue and she sadly turns away. Chartreuse is powered by an Arduino Uno, two servos, and a stepper motor and
Back Story My brother has Funko POP figures that represent his characters that his friends play most often in video games. We thought that it would be cool if they had a display case that would have LEDs in it to represent their status on Steam. So with my previous experience with Arduino, Steam API,
Summary This PCB (Printed Circuit Board) resembles the YouTube Play Button award that is given out to creators for reaching certain milestones such as 100,000, 1 million, and 10 million subscribers. When the switch is turned on, the user can scroll through 5 different modes by pressing the button on the top left corner. The
A couple of weeks ago I presented my culmination project, framed laser harp, at New York City College of Technology. Work on it was so interesting for me, that I decided to share it here. I am an Arduino amateur and don’t have any professional experience in electrical engineering or programming. Neither am I a
In this short tutorial you will learn how to make an Arduino-powered LED matrix. Unlike several other designs, this one uses a “companion” computer to notify the Arduino which LEDs should be powered. I have provided the code for the Arduino, as well as some Java code for displaying text on the LED matrix (this
This instructable will teach you to build a simple Arduino based Voting machine using simple components such as push buttons and LCD. The highlighting feature of this system is that Serial Monitor in Arduino IDE is used to perform the polling operation no other external applications needed. Key Features: Every step of polling operation will
Join me in creating ground effect lighting for my scooter using a bluetooth microcontroller and addressable LED strip. For this project I’m recycling two bits of pixel strip leftover from my old POV bike project tutorial. These are APA102s or DotStars, but you could totally use Neopixels for this project, I just happened to have

The following code and library are compatible with arduino software 1.0+ ONLY. You can download the newest version of the arduino software here. When you start to talk about biometrics in electronics, heart-rate is usually the first thing to come up. And why not? I think it is often the thing we are most aware
