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 […]

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

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

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

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

Now, you can easily track attendance and clock working hours with the help of this easy and fun to make DIY fingerprint scanner! We’ll be using ThingSpeak to store and retrieve the data. All you require is a cardboard piece, some colored paper, a fingerprint sensor, evive, and lots of DIYing! Ready for some scanning
Ever tried to get out of bed quietly at night only to trip over something and wake up the whole house? Motion sensing night lights installed discreetly under your bed provide low-level light bright enough to guide you around those stray LEGO bricks but dim enough so you’re not woken up fully. As well as
