DIY Rotating Digital LED Display Module Alarm Electronic Digital Clock Kit 51 SCM Learning Board 5V DS1302

DIY Rotating Digital LED Display Module Alarm Electronic Digital Clock Kit 51 SCM Learning Board 5V DS1302












Rotating LED electronic clock

Features: The electronic clock adopts the principle of digital tube display design, adopts the design of plug-in components, and has high success rate. Contains six Time animation, effective display of time and various functions. LED flashing light includes four offline animation display modes, lighting effects The fruit is very decorative, bringing a good aesthetic to the home and table. The electronic clock is alternately displayed with time and temperature. Precise and with power-down memory travel time function. With an alarm clock function, it can be turned off. With light control function, according to the environment Adjust the brightness.

Circuit principle:

Using single-chip microcomputer as the main control, use DS1302 travel time chip to provide accurate travel time clock source, combined with digital tube And LED lights show specific time values. Combined with the temperature light intensity detecting element, it can achieve the brightness adjustment and temperature check attached. Test function. The control button of the single chip is combined with the necessary key input adjustment function, and the clock sound is processed by the single chip and then beep.

Common problem:

1. The welding sequence is wrong. It is recommended to solder the LED lamp first, then solder the back component, solder the digital tube, and finally insert the chip. 2. LED lights pay attention to the positive and negative poles, long legs and positive poles. 3. The chip notch and the base notch must be consistent with the notch identified on the board. 4. Buzzer pay attention to positive and negative poles, long foot positive pole, resistance resistance value to follow Consistent on the logo. 5. The triode should be inserted in the same shape as the board. 6. The digital tube pays attention to the direction, and the decimal point is below. 7. Power supply pay attention to the positive and negative poles, the power supply DC voltage is 5V. 8. Check for solder shorts and solder joints. This phenomenon is common. 9. If the display is abnormal or the time is not gone, remove the DS1302 and buttons. Battery, then plug in the DS1302, do not plug in the battery, and then power on, Put the battery on after normal. 10. If the individual lights are not lit, check the solder shorts of the unlit lights and Soldering, check it, and change the light if it is not lit. 11. If the four digital tubes have the same segment code that is always on and highlighted, Some LEDs are also always on because of an electrostatic breakdown of an LED. a digital tube that causes a single-chip pin to share with this lamp.

6-Bit DIY Electronic Kits Digital Clock Soldering Practice for School Science Project Student STEM Project for Learning Teaching

6-Bit DIY Electronic Kits Digital Clock Soldering Practice for School Science Project Student STEM Project for Learning Teaching

DC 9V DIY Kits C51 Electronic Digital Clock Alarm/Countdown/Stopwatch/Counter Function Soldering Training Suite


Specification:

If you weld the components correctly, generally you can use it normally, the operating voltage is DC 7V - 12V (Typical applications is 9V), pay attention to the polarity when connecting to the power supply.During operation, continuous short time (less than one second) press S3, you can make a continuous cycle option in the following six functions. Meanwhile for the long press (more than 2 seconds) S3, then return to the clock function model immediately.


Function:

1. Clock function: display 10:10:00 after connect to power

2. Correcting function: short press S3 once, namely with the flashing current time and the colon status, after that press S2 means hour plus one , press S1 means minutes plus 1, seconds are not adjustable .

3. Alarm function: Press short twice S3, namely display status is 22:10:00, colon is long-bright. Then press S2 means plus 1 hour, then press S1 means minutes plus 1, seconds are not adjustable . When hours are more than 23 the screen will be displayed - : - : - , this means closing the alarm function.

4. Countdown function : Press three times S3, show a status of 0 , colon as long off. Press the S2 then from low so high to display, press S1 means plus 1, when press S2 to the six times it will begin to countdown based on the time you set up, press S2 again will re-enter the adjustment function, and stop the countdown .

5. Stopwatch function : Press the S3 four times, with display status of 00:00:00 , colon as long bright .Stopwatch is started by pressing S2, S2 is pressed again to end the stopwatch, after you finish the stopwatch, after S1 is pressed the stopwatch is cleared.

6. Counter function : short press S3 five times, with the displays status of 00:00:00 , the colon is long off, the counter is incremented 1 by pressing S2 , press S1 again the counter is cleared .
