Ordinary digital cameras work by using a large array of light sensors to capture light as it is reflected from an object. In this experiment, I wanted to see whether I could build a backwards camera: instead of having an array of light sensors, I have just a single sensor; but I control each of

One of the things I look forward to with summers in Pennsylvania are fireflies in my backyard. I recently taught myself Adruino programming for the purpose of making this simple project. It’s a great program to start with and is easy enough for any programmer, novice to expert, to build, modify and have fun with

The education and home market is flooded with modular electronics ‘learning’ systems designed to teach kids and adults key STEM and STEAM concepts. Products such as LittleBits or Snapcircuits seem to dominate every holiday gift guide or parent blog for educational toys. However, these systems always come with a hefty price tag attached and many

The Super Mario games were my childhood. I’ve always wanted to have some of the props in the games, and now that I have the tools to do it, I decided to start making them. The first up of that on my list is the Question Block. I managed to make the question block so

In my first Instructable Motion Activated Automatic LED Stair Lights with Arduino I mentioned the use of “Cooperative Multitasking”. So what is it and why is it helpful? This Instructable attempts to answer the “what is it” and “why is it helpful” question with a simple example that step by step builds up into a more complex
Cooperative Multitasking on Arduino – With Pretty Blinky Lights! Continue Reading
WhatThis button pad is made using a PCB and other components manufactured by Sparkfun. It is driven by an Arduino Mega. Each button is nice and squishy and satisfying to press, and it has an RGB LED inside! I’ve been using it to control animations I’ve coded in Processing. The button pad sends a message

Like many older people, my mom lives by herself. She likes her lifestyle but sometimes it gets a bit lonely. We talk on the phone a few times each week but it’s the in-between times where she could use a little emotional boost. A simple “I’m thinking of you” would be enough to make her

Have you ever wanted to turn the lights ON or OFF just by thinking about it? Or do you want to know how stressed you are by looking at the color of a RGB led? While now you can by following this Instructables! To get a feeling for what we are going to make today
In this instructable i will explain how to connect 7 segment display, decoder and arduino. It´s pretty easy. At first we have to learn something about decoder. I´m using BCD to 7 segment decoder. My is D147D, this is old chip, but the newer are similar. Documentation about one of them you can find here
Arduino and 7 segment LED display decoder Continue Reading
Three years ago I saw “My New Flame” by MORITZ WALDEMEYER, INGO MAURER UND TEAM 2012 at the museum gift shop, and feel in love with the idea. I hoped to recreate something mesmerizing, enjoyable, functional and interesting to watch, but with a slight twist. I certainly couldn’t make anything comparable to the their beautiful work of art.
