Hi there, This is my contribution to the Space-Contest. There are some ISS-Pointer around the WWW. Some of them use several PSUs and/or quite big motors. My goal was to build something cheap, looking cute and a little bit badass – all powered with only one 5 Volt PSU. If the GIF and/or the embedded Video don’t work, here […]
Let’s learn to adjust an LED’s brightness using one of the Arduino’s analog outputs. You’ve probably already learned how to use Arduino’s digital i/o pins to send HIGH and LOW signals to an LED, but some of these pins are capable of simulating a signal somewhere in between. These pins are labeled on the Arduino Uno […]
You’ve all probably had a chance to do that classic high-school experiment: pop bottle rockets. You’ve probably taped on some fins, a paper nosecone, and presto! You launch a “rocket” that is loads of fun- and watched it fall down from the sky. Why stop there? Here, I’ll show you the basics of building the […]
After building some of these: https://www.instructables.com/id/Matrix-LED-Light/ i’ve decided to bring the candle onto another level. While the first one looks good, it does look a little bit too much like the original. Nothing against the first design. It looks cool and modern. My new approach is a little bit warmer and uses different materials. Still […]
During my high-school sophomore year, the 3rd floor of our house lighted on fire due to a short circuit. Fortunately, my family was away on vacation for Christmas. But if we were home, wouldn’t it be crucial to tell the direction of fire quickly so that we know the direction to evacuate? Consider another situation. […]
Isn’t it nice when you can hit two birds with one stone? That’s exactly what we’ve done as we approach both Arduino Day and Saint Patrick’s Day with our version of the Chug-O-Meter! We absolutely loved what the circuit.io team did with their Chug Meter but thought that we could add more to its survivability […]
A friend introduced me to neopixels (WS2812) programmable LED’s. That would be great for my word clock, so I re-did the clock. It is very much a mixup with a slightly different size and code. The 8×8 WS2812 modules are also cheaper than the colorduino, I used before. Check out my previous Ible if you want to […]
The problem that fix this project is the following: at the high school where I work, the class-change bell doesn´t sound loud enough everywhere and sometimes it causes some problems. Install a new wired class-change bells or buy a wireless bell system isn´t possible by the moment. This project could be useful too, for everybody […]
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 […]
This project is an extension or remix of my original Portal Turret on Instructables (Portal-2-Turret-Gun). It can also be used as a cheap controller to control anything that uses the nRF24L01 radio chip. The LCD screen is particularly useful when customizing. (It turns out to be quite useful in checking when my radios establish and […]
