We mean to say that we will need a decimal coded output in many cases rather than a raw binary output. We have many counter ICs available but most of them produce binary data as an output.
We will again need to process that output by using decoders or any other circuitry to make it usable for our application in most of the cases. Let us now introduce you a new IC named IC It is a CMOS decade counter cum decoder circuit which can work out of the box for most of our low range counting applications.
It can count from zero to ten and its outputs are decoded. This saves a lot of board space and time required to build our circuits when our application demands using a counter followed by a decoder IC. This IC also simplifies the design and makes debugging easy. It has 16 pins and the functionality of each pin is explained as follows: Pin It is the output 5. It goes high when the counter reads 5 counts.
Pin It is the output 1. It goes high when the counter reads 0 counts. Pin It is the output 0.
Pin It is the output 2. It goes high when the counter reads 2 counts. Pin It is the output 6. It goes high when the counter reads 6 counts.
Pin It is the output 7. It goes high when the counter reads 7 counts.
Pin It is the output 3. It goes high when the counter reads 3 counts.

Pin It is the output 8. It goes high when the counter reads 8 counts. Pin It is the output 4. It goes high when the counter reads 4 counts.
Pin It is the output 9. It goes high when the counter reads 9 counts.
Pin This is divided by 10 output which is used to cascade the IC with another counter so as to enable counting greater than the range supported by a single IC By cascading with another IC, we can count up to 20 numbers. We can increase and increase the range of counting by cascading it with more and more IC s.
All the source code files are copied into one large lcd. The menu is built up using two switch-case loops. The has a clock pin and a reset pin. All the s clock pins are connected to different pins on the microcotroller.

All the reset pins are tied together and connected to one pin on the microcontroller. With this configuration I can clock individual ICs. Since all the reset pins are tied to one pin on the microcontroller, I only have to pulse that pin high to reset all ICs.
Navigating through the menu, is done with a push button. To you, one push might look like one push, but to the microcontroller there's a different story.

I'm dealing with this in the software. You have 14 different patterns in the software. You can download the source code in the link below. A total of 32 LEDs are running up and down, or in different patterns.
Are you up for it? SOT transistor and a resistor: I made four of these boards: This is the controllerboard:.Switch D: This is switch C,, with the clock pin helt high, and pulse low: Click on images for better resolution. You can download the source code in the link below.
Pin It is the output 4. Pin It is the output 4.
I made this circuit a few years ago in the shape of my first letter D but I have de soldered it some time ago when I was badly in need of LEDs for some other project. This saves a lot of board space and time required to build our circuits when our application demands using a counter followed by a decoder IC. This IC is very useful and also user friendly.
