Pre-Confirmation to our Project ( Digital Alarm Clock)

Pre Confirmation to our project 
Hye Guys, great to have all of you right now because we already have the final pre confirmation of our project to share after having a meetings on this project.…We together have decided to choose this idea as our main electronic digital project.Here are the pre-confirmation of our final project for this subject. Check it out guys! J

Here are the list of components that will be using in this project :

1) IC LM8560

The Function of this component is :

The LM8560 is alarm equipped digital clock IC with built-in driver capable of directly driving LED display equipment.

Single chip P-channel ED MOS LSI;

LED direct drive using time division (duplex configuration);

Wide operating power supply voltage range;

Built-in alarm function with 24-hour control;

Supports changeover between 12-hour AM/PM and 24-hour displays;

Built-in battery backup CR oscillator;

Users 50Hz or 60Hz as standard frequency;

Built-in automatic fast forward function for hour and minute settings;

Built-in sleep timer function (maximum intervals of 59 minutes or 1 hours and 59 minutes);

Built-in snooze function supporting repeat use;

Equipped with power failure display function;

900Hz output for alarm tone  


2) Relay

- relay mainly has the following functions:

1) To enlarge the range of control. E.g., when the controlling signal of a multi-contacts relay reaches a certain value, according to the different forms of the contacts, it can synchronously change over, close or open several circuits.

2) Enlargement. E.g., sensitive relays and medium relays can control a high-power circuit with minute controlling power.

3) To integrate signals. E.g., when several controlling signals are put into a multi-winding relay in the stated form, the relay can realize the expectant controlling function by analyzing the different signals.

4) Automatization, remote control and monitoring. E.g., in automatic equipments, the relays and other electronic components can constitute program-controlled circuit, realizing the automatic operation.

3)Step Down Transformer 6V

4)Capacitor 

Capacitor's function is to store electricity, or electrical energy.
The capacitor also functions as a filter, passing alternating current (AC), and blocking direct current (DC).
This symbol  is used to indicate a capacitor in a circuit diagram.

The capacitor is constructed with two electrode plates facing eachother, but separated by an insulator.

When DC voltage is applied to the capacitor, an electric charge is stored on each electrode. While the capacitor is charging up, current flows. The current will stop flowing when the capacitor has fully charged.
