    No need for buttons with this Arduino Cloud alarm clock

    Reading Time: 2 minutes

    When Arduino first hit the maker scene, the world of embedded electronics was largely unconnected and offline. But as the IoT, home automation, and smart technology advanced, Arduino kept up. Today, there are a variety of Arduino development boards that offer built-in networking capability and you can use the Arduino Cloud to take advantage of them. To demonstrate that, Doug Domke built this button-free alarm clock.

    User interface design is a complex field that has to balance usability, simplicity, and practicality. Take a look at the radio alarm clocks of the 1990s to see how bad user interfaces can make device interaction frustrating. Domke’s alarm clock goes in the complete opposite direction and omits buttons altogether. It lets the user “set it and forget it” through a simple Arduino Cloud dashboard. The time automatically updates based on the configured time zone and daylight savings settings.

    This requires very little hardware. Power comes in through USB to an Arduino Nano ESP32 board, with a connected piezo buzzer module and four-digit seven-segment display. Those fit inside a basic 3D-printed enclosure. All the magic happens through the Arduino Cloud and Domke explains how to set up an Arduino Cloud account, create a dashboard, and connect the Nano ESP32 to that dashboard.

    If you want a dedicated alarm clock, this is a quick and easy project that will help you get acquainted with the Arduino Cloud for future IoT projects.

  • Smart bedside mat won’t let you snooze your alarm

    Smart bedside mat won’t let you snooze your alarm

    Reading Time: 2 minutes

    There is one thing that we can agree on: more sleep is better. None of us want to wake up, which makes that snooze button oh so tempting. That leads to the inevitable cycle of pushing the snooze button over and over again until suddenly you find yourself let for work or your kid’s school drop-off time. Many people have tried to find solutions to this problem over the years, but we like Arpan Mondal’s Smart Wake-Up Mat.

    This is a small mat designed to sit by the user’s bed. When the alarm goes off in the morning, the user must get out of bed and stand on that mat for five to 10 seconds. Until they do so, the alarm will continue blaring. Snooze is not an option here and the simple act of getting out of bed and standing up should be enough for most people to shake the sleep off, ensuring that they won’t fall back asleep. Best of all, this is affordable and easy to build.

    The clock is an Arduino Uno board, which has onboard timekeeping accurate enough for an application like this — though it will drift eventually without the use of an RTC (real-time clock) module. The alarm sounds through a piezo buzzer. Instead of an expensive and finicky load cell, the Smart Wake-Up mat utilizes a custom sensor. It is essentially a big button made of aluminum foil sandwiched between sheets of cardboard. A mat of the user’s choice covers that. When the user steps on the mat, they push down the foil so it makes contact with a wire, completing the circuit.

    If you have trouble getting out of bed in the morning, this is a great solution.

  • Remind-Ino is an alarm clock for everything

    Remind-Ino is an alarm clock for everything

    Arduino Team — March 23rd, 2021

    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.

  • Defusable Bomb Alarm Clock, better leave that Home!

    Defusable Bomb Alarm Clock, better leave that Home!

    The Defusable Bomb Alarm Clock may be something you’d want to leave at home, but it’s still a fully-functional alarm clock with a beeping alarm, snooze alarm, etc. Once the red button is pushed, a countdown sequence begins, just like something you’d see in Hollywood movies. The wires are attached with screw terminals, so they can be easily replaced, or if you don’t want to actually cut the wires, simply pull them out of the terminals.
