Lm8361 clock circuit


When you hear about the alarm clock circuitthe first thing that may come to mind is the alarm clock. No doubt, you're correct, but the device also works for other applications we'll discuss later in the article. The circuit helps you shun your alarm clock for the weekend after a long week. And this is no surprise because the circuit has a real-time display, sleep timer, snooze functions, etc.

In summary, it's a fun project to jump on if you're looking for a simple alternative that relates to time. It's a simple electric circuit that notifies you of an intruder, system malfunction, detected condition, and other fundamental concepts regarding intrusions. So, you can use the devices in different applications like:.

Before we give you a glimpse of the alarm clock circuit diagram, here are the components that will get you started:. With the diagram in mind, let's take a look at the design.

Circuit Diagram of the alarm clock. The IC1 is one of the basic concepts of the circuit as its drivers help activate the duplex LED digital display signal that displays the time. So, the LM supports 12 and 24 HR time formats, and it shows snooze function, current time, and alarm support. This component comes in handy for showing different information like alarm notification, current time, etc.

So, the LED display saves you the stress of using extra drivers with electronic systems to initiate the display unit. And it's because all the drivers you need are in the alarm clock IC. The IC2 helps drive the alarm buzzer. Plus, the audio power amplifier low voltage gets power via a potentiometer that receives a signal from the LM 's alarm output.

With the S1, S2, S3, and S4you can do three essential things: turn off the alarm, set time, and set the alarm. Further, you can also use these components to set your alarm time in hours and minutes separately.

Searching for LM8361 Clock IC: Pl Help

An audio power amplifier is responsible for initiating the buzzer. And it helps to signal an alarm at a set time. Each of the diodes has a specific function. For instance, the D1 combines with the C1 capacitor to generate a direct current. When this happens, the voltage goes to the LM IC1.

Plus, they also contribute to the LM 's input. The transformer is functional when stepping down a high AC supply V to about 12V alternating current. First off, this alarm clock circuit is more like a simple one. When the mains' input moves to the transformer, the component helps to change the input voltage to a 12V AC signal. Then, it supplies the IC1's Vdd Pin And it does this by using the resistor R1 to the IC1's Pin Further, the diodes D2 and D3 give conforming inputs to the display's cathode.Forums New posts Search forums.

GPS Projects. Internet and LAN Projects. Interfacing USB Projects. Sensor — Detector Projects. Motor Based Projects.The use of digital alarm clocks has increased over years with development in electronics. The advantage of digital alarm clocks over analogue alarm clocks is that they require less power, the time can be set or reset easily and displays the time in digits.

Design of a simple digital alarm clock is explained here. Using this digital alarm clock, time can be displayed in 24 HR format using an LED display and alarm can be set to a specific time.

Digital Alarm Clock IC Chip

The heart of the digital alarm clock is the IC LM It is an alarm equipped digital clock IC. It is a low voltage audio power amplifier. It is used in the circuit to drive the alarm buzzer. The alarm output of the LM is given to power amplifier through a potentiometer. In the digital alarm clock, to display the information like current time, alarm notification etc. There is no need for any extra drivers to drive the display unit as all the required drivers are built in to the digital clock IC.

These four switches are used to set time, set alarm and turn off the alarm. When setting time and alarm in the digital alarm clock, both Hours and Minutes can be set separately using these switches. Diodes D2 and D3 act as switch signal generator to the cathode of the duplex display. They work in relation to the input of the LM The bra dop function of the digital alarm clock is to signal an alarm at specified time.

A buzzer is used for this purpose which is driven by an audio power amplifier. A digital alarm clock is a very useful device as it can display the current time as well as function as an alarming device. The circuit shown above can act as a simple digital alarm clock without requirement of any programming.

The components required and the complexity of the circuit are less. The working of the above shown digital alarm clock is as follows. As explained in the component description, the heart of the digital alarm clock circuit is the digital clock IC LM The input from the mains is given to the transformer which converts the input voltage to 12V AC.

This signal can be supplied from the mains supply using the resistor R1 to the Pin 25 of the IC1. In relation to the input of the IC1, corresponding inputs to the cathode of the display are given through the diodes D2 and D3. After switching on the power, we need to set the time. This is the current time to be displayed. In order to set the current time, we use the switches S1 and S2. Switch S1 is used to set Hours and S2 is used to set Minutes.

LM automatically triggers the display connected to it and the time will be displayed on the duplex LED display. The duplex display is a 4-bit seven segment LED display, where two bits are for displaying the Hours and two bits are for displaying Minutes and the Hour and Minute bits are separated by a colon.A monster Martian Clock immediately springs to mind.

My e-mail is at the bottom of the page. I would be also interested if you have built the clock - if so, I will appreciate any pictures from your project and would be glad to post them on this site, or to put up a link to your site.

Finding the right enclosure for a project is often surprisingly difficult. You can make a nice box yourself if you have the tools, or you can buy a ready-made enclosure from places like RadioShack.

My favorite approach, however, is to give new life to some old device - a modem, a computer mouse, whatever, - then to take out what I don't need and to keep anything I can re-use. In this case, a friend found for me this beautiful dialup modem from a long-gone era:.

As a bonus, it had all the connectors I might need, and significant part of the electronics of the modem can be reused. Time to take out the 10x magnifying glass and reverse engineer the schematics for the power supply on the board, and the amplifier circuits for the internal speaker.

Another potentially useful thing are the LEDs in front, along with their driver chip I haven't used the LEDs in this project yet, but decided to keep them, just in case.

The rest should be taken out. Time to decide what to do about the ports at the back. The main connector can be used to re-program the PIC without taking it out of the box. To do so, I attached some pin connectors to the internal side of the DB leads so the microcontroller board can be plugged in there later:.

Glamheart xvideos comes putting connectors to tap the stabilized 5V of the modem's power supply electronics. Another connector attaches to the modem's internal speaker amplifier an easy to find LM Finally, I added a 9V connector for the rechargeable battery, along with a simple trickle-charger composed of a 2. To plug it to the PICKit2 programmer, I took apart a printer cable and did some very mean things to it:.

The board where the PIC and the rest of the electronics will sit is quite simple. Since we already have the speaker amplifier and the power supply, what's left is mostly connecting wires.

Here is the board, in all its red-and-black glory:. Time for some drilling and filing to attach the keyboard and the LCD module with its backlight switch. Attaching the keyboard and the backlight switch was easy. Making sure that the opening for the LCD module is the exactly right size and accurately positioned was not. But with some care, the end result was quite satisfactory. It starts to look like Monster Martian Clock already.

After some hard programming, a few sleepless nights, and just a bit of magic, it is finally complete:.

The clock display is a 2x16 LCD module. The first row always shows the currently selected timer. The second row is used to show either the Julian time, or the current menu selection:. Here, TmA is the name of the timer, followed by the current ichthammol ointment cyst extraction highly recommend this clock circuits features to work for less than the original circuits.
