Electronic Hourglass with 57 Blue LEDs

Description

Discover the magic of time with this electronic hourglass kit! Made up of 57 blue LEDs, it simulates the flow of sand in a traditional hourglass thanks to an integrated microcontroller.
Customize the speed of time with a simple button: each press changes the flow rate, making this device not just a decorative object, but also an interactive one.
Perfect for electronics and DIY enthusiasts, the kit includes all the necessary components for an easy and rewarding assembly.

Powered at 5 VDC, with compact dimensions of 84x40x10 mm.

Note: The integrated circuit is in SMD version.

Assembly and Use

To assemble the kit, it is recommended to start with the components of the smallest thickness, so proceed by mounting the socket, paying attention to polarity. Then proceed with the slide switch, the button, and then the LEDs. For the LEDs, polarity is also very important, so make sure it is correct, because if reversed, during operation, some LEDs might not light up correctly.

Once assembly is complete, power the product (5Vdc) via the DC1 connector (center positive), or by soldering two wires to the two pads located between the DC1 connector and the S1 switch (with the DC1 connector on the right, the left pad is positive, the right one negative). If the device does not turn on, check that the slide switch S1 is in the ON position. The S2 button can be used to change the flow of time.
