What is the use of Johnson counter?

Johnson counter is used as a synchronous decade counter or divider circuit. It is used in hardware logic design to create complicated Finite states machine. ex: ASIC and FPGA design. The 3 stage Johnson counter is used as a 3 phase square wave generator which produces 1200 phase shift.

What are parts of a digital clock?

Clock Station (main or primary clocks). Secondary clock (analog or digital clocks). Radio time signal receiver (DCF), wired channels or satellite time signal receiver (GPS). Antenna for receiving radio or satellite time signals.

How do you make a clock with cardboard?

Clock design instructions:

1. Flip the plates upside down on the cardboard and trace them with pencil onto the cardboard.
2. Then, cut the circles out.
3. Glue colored construction paper onto the front to make the face of the clock.
4. Use a ruler and start by marking 12, 3, 6, and 9 on the small circle.

How do you make an alarm clock in little?

What can I use instead of a brad fastener?

You can use a pin, craft knife, or any other pointy tool that you have handy; place paper on the underside of an old mouse pad, and make a hole right where you want to place your brad.

What is the size of a digital clock without a microcontroller?

This is a Big digital clock circuit without microcontroller for large size: 6 CM, cause can see clear on Very clearly in the range of 10 meters, even in the dark, because the display is easy to read numbers. This projects use all CMOS ICs that easy to buy in store than the Cheap Digital time clock with alarm circuit by LM8560

How does a jumbo digital clock work?

Figure 1 is block diagram of jumbo digital clock circuit. Therefore, when the 3000 counter circuit counts wave of 3000 cycle (1 minute). Then it will send the signal to a sixty counter circuit to add the numbers in the minutes digits of the clock in one step.

How does the 3000 counter circuit of a clock work?

Therefore, when the 3000 counter circuit counts wave of 3000 cycle (1 minute). Then it will send the signal to a sixty counter circuit to add the numbers in the minutes digits of the clock in one step. Next recounts in 3000 cycle. Then send to the sixty counter in new continuously until to 59 digits, then will reverse into 0 number new.
