LM – Digital alarm Clock – DIP

Sujjwal 21 Jun Reply. Please give the pcb layout size for printout on glossy paper. The advantage of this design is that it allows to use less wires to connect the display to the board. And the lm850 out signal from pin 17 that you can continue to use, to control another circuits.

I started out trying to simply fix some broken hardware mounts that hold the display and button mechanism within the alarm clock that looks like the Scooby-Doo Mystery Van. Please suggest what can be done in this scenario. Fortunately there’s a simple fix available.

This will prevent oxidation of the copper. Hi lm85660, Here is PCB layout: When the time limit, the alarm signal lmm8560 ring. By using our website and services, you expressly agree to the placement of our performance, functionality and advertising cookies. Hi duplex display is not needed, if you have interface. Lekshmanan 20 Mar Reply. The chip can drive the LED display directly. Shawn 10 Oct Reply.


Info on the code is no longer available. This project is easier than one: The digital clock circuit that electronic amateurs are most interested. And it’s old, really old.

This process is repeated fast enough that our eyes see the complete image. A few days later, it started to lose time, but kept running. 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: In the 1st picture i want to know, what S1 is?

KH 19 Nov Reply. The 50 Hz or 60 Hz pulses from the mains are used instead of an external oscillator, probably to keep things simple and thus cheap. Next Post LM alarm digital clock for beginners.

Digital clock alarm based on the Lm8560

Unfortunately, it turned out that the chip-onboard which produced the honking sound was shorted internally lm860 some transistor overheating and the dim display.

Samad Lm850 3 Jun Reply. I used a 2 x 6V one, rated at mA so it doesn’t get too hot. Cheap Digital time clock with alarm circuit. Chin 9 Nov Reply. DrinkTea July 15, at 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.


LM Datasheet pdf – Digital Alarm Clock – SANYO

Thanks for your story and all the detail. Many electronics circuits and projects for learning in simple ways. They are a hot item on eBay. Jared Ireland 5 Dec Reply. A lm560 days later, I noticed the display blinking on and off. Ng Zhun Khai 17 Feb Reply. The schematic Since I was in need of lj8560 easy to read clock, I decided to make one with this chip.

Press switch S4 to set minutes, Time to show the remaining time. I highly recommend this clock circuits features to work for less than the original circuits.

I decided it was best to let it go, as the IC chip was most likely damaged. 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. Regarding the display mode, the current build shows the time in military format 24H. Newer Post Older Post Home.
