Shawn 10 Oct Reply. KH 19 Nov Reply. Have a great day…! When the power is out, the chip will activate an internal Hz oscillator that uses C3 and R4. In case you want ln8560 build the project and you can’t source a suitable common cathode duplex display, here’s the electrical schematic of one that’s tested to work: Press switch S5 to set hours.

Might be due to voltage drop. The circuit modifications may not have been the cleverest or the best solution, so ml8560 you have other suggestions please leave them in the comments below. Press the switch S6 to set hours.

Julius 15 Jul Reply. Press switch S4 to set minutes, Time to show the remaining time.

Digital clock alarm based on the Lm

One disadvantage of this design is that the clock will only be as accurate as these oscillations are close to the rated value. According to the datasheet, it it a 4-digit clock IC that l,8560 a duplex LED display to show the time.

Some other details The chip can work with both 50 Hz this is llm8560 I used or 60 Hz mains frequency. Hi, would this circuit work on 5v and how much power it consumes. When the time limit, the alarm signal will ring. The alarm signal from pin 16 of IC1, will be entered to the potentiometer P1 Volumeto pin 3 of IC2 LMthat is alarm signal amplifiers to drive the loudspeaker.

To set the alarm time 1.

But lm5860 will not display on the screen. What is the purpose of LM in this circuit. To set the time turn on- off the Electric appliance. This process is repeated fast enough that our eyes see the complete image.

Hi, John Lj8560 can find at amazon. You can leave pin 26 disconnected for 60 Hz, or leave it grounded to use it at 50 Hz with care, as ground is VSS here.

A few days later, it started to lose time, but kept running.

Digital clock alarm based on the Lm8560

One of the coolest features of the alarm was that it made a car honking noise when the alarm was activated. But they are fantastic clocks. Leave a Reply Cancel reply. Press the switch S4 to set minutes. Quote and Order boards in minutes on https: Can you send me a copy of the PCB layout? So when half of the display is on, the other half is off. That being said, here are the schematics and a PCB for the clock: Without the backup battery, the time will simply reset. Figure 3 The components layout of this projects.

I have a small lamp plugged into the same circuit. Related Posts LM alarm digital clock for beginners CD Timer Circuit 22 seconds to 4 hours minuts timer circuit using IC Automatic water level controller — 2 circuits choice Simple touch switch using transistor.

You can also go with a 2 x 7. It’s best to keep the power consumption to a minimum, especially if discrete LEDs are used for the display for details consult the datasheet available here: Learn how your comment data is processed. Ng Zhun Khai 17 Feb Reply.

The only difficult part was finding a suitable display duplex LED, model S. Askar Alibolandi 29 Jun Reply. And it’s old, really old. It also damaged my clock. The brightness of the display can be adjusted by changing R1 and R2 increase their value to make it dimmer. Thanks for your story and all the detail.

The radio still worked, so I moved it to another room and plugged lm85600 in. I used a 2 x 6V one, rated at mA so it doesn’t get too hot. From the time stamp, it looks to be made in the third week of And the sleep out signal from pin 17 that you can continue to use, to control another circuits.
