At a glance, a digital clock can be used to tell time.They were more popular than the older sweep hand clock.The time was derived from either a pendulum or a spring.Pendulums can't be used on moving platforms due to their slow release of tension.The mechanical time bases were presented in a mechanically driven display with the use of sweep hands.With the perfect use of multivibrator chips, electrical circuits could be built that could accurately keep time under a wide range of conditions.The time display had to follow suit as the time base had switched from mechanical to electrical.7 segment displays allow the time to be shown numerically.You can build your own clock from components.Follow the tips to learn how to make a clock.
Step 1: There is an electronics parts supplier.
Suppliers can be found on the Internet or through electronics supply catalogs.A vendor that offers basic integrated circuits of the generic 74xx and 40xx families is a good choice.
Step 2: Acquire a prototyping board.
The required clips should be purchased if the breadboard does not come with them.
Step 3: Get the data sheet for the regulator.
The data sheet will show how to connect the components.
Step 4: A 5 watt power source can be created.
If you want to build components, you need to acquire the 7805 and support it.To get the pin-to-pin wire connections for this circuit, you need to consult the manufacturer's data sheet.To support the components, plug them into the breadboard.
Step 5: Define a time base.
The 4060 multivibrator integrated circuit has a data sheet.The 4060 can be used as a time generator in conjunction with a 4013 flip flop IC.The data sheets will show the wiring of the support components.
Step 6: The time base can be generated.
Acquire the 4060, 4013, and all the other components identified in the data sheets.The time base needs to be built on one corner of the board.To get the required pin-to-pin wire connections for this circuit, you need to consult the manufacturer's data sheet.The components should be plugged into the breadboard.
Step 7: The clock needs to be prepared.
The counter ICs are in a line.There is a display driver IC in a line.The digits of a digital clock should be side by side as the Mount 6 light emitting diode displays in another line.All of the devices have to be plugged into the breadboard sockets.
Step 8: The display drivers need to be connected.
The 7490s and 7447s can be wired to the displays.
Step 9: The counter section should be created.
Refer to the data sheets.The first 4 7490s are wired from the rightmost device to the left most device.The sixth and fifth 7490 should be counted by 2 and 1 for the 12-hour clock.The fifth and sixth 7490 should be counted by 4 and 2 for the 24 hour clock.
Step 10: The time clock signals should be sequence.
The clock input of the first 7490 needs to be connected to the 1 Hz time base.The second counter is 7490.The wire pin 11 of the first 7490 goes to the second 7490).The counter is tens of seconds.Set the minutes section of the counter.Plug the output from pin 8 of the second 7490 into the normally closed contact of a single pole double throw switch.The normally open contact of the switch needs to be wire.The switch has a clock input.The minutes counter is 7490.The wire pin 11 of the third 7490 is the clock input.The counter is tens of minutes.The hours section of the counter should have the ability to be set.The output from pin 8 of the fourth 7490 should be connected to the normally closed contact of a single pole double throw switch.The normally open contact of the switch needs to be wired.The clock input of the fifth 7490 needs to be wired.The hours counter is the fifth.You can connect pin 6 or pin 7 of the fifth 7490.The counter is tens of hours.Pin 6 is used for the American 12-hour clock.The European clock uses pin 7 of the fifth 7490.
Step 11: Attach the battery to the regulators using the 12 volt battery sockets.
