Who says an alarm clock just has to beep, or annoy you in the mornings? Certainly not MakeUnited, who’s put together an Arduino Nano verbal reminder project over on Instructables. His device lets you program a whole bunch of alarms that each play a specific MP3 file.

The REMIND-INO is styled to look like a vintage radio, as the maker’s target audience is his grandparents. That being said I’m not a grandparent, and this would be an ideal way to substitute my inability to keep track of what time it is… ever.

There’s no limit to the reminders or alarms you might program into the REMIND-INO, but MakeUnited has a couple of suggestions:

  • Reminding people to perform tasks at specific times.
  • Tell stories, read books, teach cooking recipes and even play songs.
  • Keep track of appointments.
  • Anything else you might need a timely verbal prompt for.

And because it’s designed for an older demographic, he’s kept the controls super simple.

When an alarm goes off, it continues to repeat the message until you hit the big, illuminated button on top. Or after five minutes, just so it doesn’t become a major annoyance.

It’s an amusing project, as you can see from the build-along video. But it’s also easy to see how useful and practical it is. We see his grandparents being reminded to take pills, and to set off for an appointment. Alarms that anyone would find useful, regardless of age, and the verbal alert just makes it all the more effective.

The simplicity of the project would really keep the costs down too, and there’s loads of room for expansion and innovation if you wanted to build on this ingenious project.

In case you need it, here’s a reminder of where you can find the project on Instructables.

The post Remind-Ino is an alarm clock for everything appeared first on Arduino Blog.

Some of us are oblivious to how often we touch our faces. The current finding is we reach for our eyes, nose, or mouth every three to four minutes. Twenty times per hour is an awful lot of poking, picking, itching, and prodding when we’re supposed to keep our hands away from glands that can transmit and receive disease. To curb this habit and enter the 2020 Hackaday Prize, [Lloyd lobo] built a proof-of-concept device that sounds the alarm when you reach for your face.

We see an Arduino Uno connected to the classic HC-SR04 ultrasonic distance sensor, an LED, and we have to assume a USB battery pack. [Lloyd] recommends the smaller Nano, we might reach for the postage-stamp models and swap the ultrasonic module out for the much smaller laser time of flight sensor. At its soul, this is an intruder alarm. Instead of keeping siblings out of your room, you will be keeping your hands out of the area below the bill of the hat where the sensor is mounted. If you regularly lift a coffee cup to your lips, it might chastise you, and if you chew sunflower seeds, you might establish a tempo. *crunch* *chip* *beep* *crunch* *chip* *beep*

We have reviewed technology to improve our habits like a bracelet that keeps a tally, and maybe there is a book that will help shirk some suboptimal behaviors.

Chad Herbert’s son Daniel was diagnosed with Benign Rolandic Epilepsy in 2014. It’s a type of epilepsy the Epilepsy Foundation says accounts for about 15 percent of all Epilepsies in children and the good news is that most children grow out of it.

The bad news is that Daniel’s most affected by his condition at night or early morning while he sleeps. That’s why Chad invested in a sleep monitor/alarm for his bed that detects when he’s having a full tonic-clonic seizure.

At the same time though, he decided to work on a DIY version of a seizure alarm  running on Arduino Micro. The starting point was Arduino’s “Knock” example project with the sketch code originally created in 2007 by David Cuartielles and modified by Tom Igoe in 2011:

While shopping around for the exact type of monitor/alarm my wife and I wanted, I found out a few things:

  • They are hard to find. I believe the one we ended up with was manufactured by a company in Great Britain.
  • They are expensive. The one we ended up getting cost in the $400-$500 range.
  • The one we have isn’t totally cumbersome, but it’s not easy to pack up and take with you somewhere.

Figuring these things out, I decided to search for a way to build a simple seizure alam that’s both relatively inexpensive and easy to transport. I’m sure there are people out there who have children that suffer from seizures that simply cannot afford equipment such as this even though they truly need it. Thanks to the folks in the Arduino community, I was able to accomplish both things I was setting out to do.

Discover how it was made on his blog.

GSM based SMS Alert Fire Alarm System using Arduino

by jojo @ circuitstoday.com

Recently we have learned how to interface GSM Module with Arduino and send/receive SMS using GSM module. Interfacing any device with a micro controller is the first step to building a useful system or project with that particular device. In this tutorial, we are going to build a very interesting project – a Fire Alarm System which will send SMS to a set of Mobile Numbers when fire occurs in a particular location. We have seen many typical Fire Alarm projects which will alert with a siren or an automatic shutdown mechanism. This fire alarm project make use of modern communication technologies to deal with emergencies.

So, first thing I did was to get the LCD and keypad working together.

For this I pretended that it was some sort of arm/disarm (or entry/exit) thing.

My code for this part is at: http://pastebin.com/YndLneqm.

Getting the LCD wired up was tricky as most wiring diagrams for it don’t show the last two pins wired up and these are required for the back light. Check my snazzy Fritzing wiring diagram to see how I wired up my LCD screen, pot (for adjusting brightness) and keypad. The pins for them all are also mentioned in my code.

Bag movement alarm for theft prevention

In short: I developed a portable, battery powered device that sounds an alarm when your bag or purse is moved. Once armed, can only be turned off by your secret code.

The device is built off an Arduino compatible Trinket Pro, using an off-the-shelf project box with PCB.

Winter is coming. So it is time to make preparations. If you live in a colder climate, you need to be concerned about the possibility of your pipes freezing. There are a lot of preventative measures that you can take such as insulating your pipes and leaving the water dripping. But for a little extra peace of mind, I designed a simple alarm that will notify me if the pipes are getting too cold and are in danger of freezing.
