In this instructable I’m going to show you how to design a kitchen timer using the Linkit One, the timer has a maximum duration of 30 minutes. And once the timer is done counting down it fires a buzzer to notify you. The time interval can be set in steps of 5 minutes and each …
This is a device that indicates by buzzing whenever the door crosses the specified distance giving a red light indication.This has been developed by linkit one board received in the giveaway! Its total cost is ~63$ including ~60$ linkit one board.Here’s video of it in action :- …
Clock generator I recently build a pulse generator and it does its job well. It produces pulses of variable length and at several frequencies. But the number of frequencies it can produce is limited and for many jobs the length of a pulse is less important than its frequency. E.g. when you are testing a …

Every digital clock has a crystal inside it to keep track of time. This crystal is not only present in the clock but also present in all computing real-time systems. This crystal generates clock pulses, which is needed for timing calculations. Although there are some other ways to get clock pulses for higher accuracy and frequency, but the …

What did I make? = This is a little project that uses ATTiny85 to make a simple “game timer”, intended to be used with board games that demand timed turns, like “Rummikub” or “Scrabble”. Never wait for all that sand getting down for the next turn again! The working is simple: – A binary preset …

Introduction We implemented a prototype for a moving alarm clock which runs away from the user when they try to silence the alarm. It has all the features of a “regular” alarm clock: settable time and alarm, snooze, and alarm on/off. The alarm clock displays the time in 24-hour format on a LED seven-segment display. …
The goal of our project was to create a persistence-of-vision (POV) analog clock using an LED display. The clock has a visual alarm system which lights up the entire display for two seconds if it reaches an alarm time. The current time and alarm times are preset into the clock before it begins to spin. …

I love the movie Stargate and when I first saw it I immediately knew I wanted to make one of the super cool Horus guard helmets. I had sketched multiple designs over the years and figured out several different methods for building it but rejected them all for one reason or another- usually due to …
The Need: Last week around at work I had another usual un-usual problem to face with. Having to make lots of mechanisms n components to work with-in seconds or fracs at times I kind-of knew this was always coming. And invariably so my poor mind couldn’t think of anything but Arduino for a handy solution …
Waking up to a buzzing alarm clock sucks. I’m one of those people who doesn’t like to wake up before the sun is out (or has been out for many hours). So what better way to make waking up fun than having a bubble party in bed! Using an arduino and a commonly available bubble …
