The idea originated from thinking about how you can create a standalone object that would be useful for someone. We thought about using LED lights to create a digital version of an everyday object which led to the idea for the digital hourglass. Creating a digital version of the hourglass allows you to adjust the timing to your needs while keeping the simplicity of the original form, a simple turn to set off the timer.
The NeoPixel LED Strip is connected to the Arduino using the 5V, digital and ground pins. Using the Arduino, it is programmed to run a specific light sequence in a predetermined amount of time.The accelerometer sensor connects to the Arduino via three separate analog pins and the 3V3 pin. Using the z-axis serial readings, the orientation is determined. This orientation value determines when and if the NeoPixel should run the light sequence.The hourglass is powered by a 9-volt battery.
