Product describe:This circuit makes use of a quartz crystal oscillator because the time base pulse oscillator, and obtains the second time base sign after digital frequency division. The time is displayed by the counter, decoder and show. As a result of the crystal oscillator is used because the time base pulse, so the time is correct.
circuit:Second, minute, and hour counter circuits use double BCD synchronous up counter CD4518 to depend and output BCD code. The BCD code shows the corresponding quantity by way of CD4511. The second and minute counters are 60-digit depend and 24-hour depend.
PCB:130x70mm double aspect. enter voltage:5V.The circuit doesn’t have a power-off reminiscence time perform, and the time must be recalibrated after power-off.
Required instruments: electrical iron: 30W-40W, solder wire: 0.8-1mm, Melting level is about 183 levels Celsius.tweezers, indirect pliers, multimeter.
Appropriate for digital DIY digital interest freshmen to be taught and observe welding.It’s broadly utilized in colleges to assist college students be taught fundamental mechanical and digital abilities.
