A Perfboard. A slide switch. I had an ATtiny micro in my parts bin and I wanted to use it for something, the thing is that it only has 17 outputs minus 2 if you use a crystal, and to control so many outputs and inputs I had to use some tricks to get around using just So I used a 74HC shift register which needs only 3 pins from the micro and gives you 8 outputs, the 74HC controls the columns and the micro scans the rows with the help of 4 transistors, and now we can control 32 LEDs with only 7 pins.
As always the only thing I left out in the schematics are the resistor values which limit the current to the LEDs, this is a thing every one does by himself. Now the negative leads are connected in a column and thats make soldering tricky because the positive rows are in the way, so you will need to make a 90 degrees bend with the negative lead and make a bridge over the positive row to the next negative lead, and so on to the next LEDs.
This is the last thing to do, to make the calculator run. I used the USBasp to program my micro but you can use any program you like or have at home. Have fun! Reply 2 years ago. Generally, it doesn't matter. You may use text editors like Leafpad, notepad, emacs, vi, ed or even the cat command. You may also use an IDE. Its truelly great project Can you please make a tutorial to decode the binary and display the numbers on a seven segment display with an IC?
Reply 8 years ago on Step 3. I'm confused. But thanks for the great instructable, I'm planning on using these concepts to make a bit led array as soon as I get my head around it! But the article is correct generally it's not the best of ideas to use just one resistor but I wanted to save some space and I had the same type of LEDs.
I've got a question: So, you're using blue LEDs and resistors with 91ohm But my question is what's the source voltage? Doesn't the voltage regulator lower it to 5V?

Therefore you should use ohm resistors - am I right? Reply 8 years ago on Introduction. Oh ok, hopefully mine work better I will update this instructable till the end of this weak, I just not home so I don't have the original project next to me. How do you read the answer lines. I'm a noob when it comes to binary as i just started learning it. By Syst3mX Vadim Follow. More by the author:. About: Electronics and LEDs what can be better?! So join me as we are going to enter the world of ones and zeros and play with some LEDs and switches along the way!
Add Teacher Note. Attachments binary calculator.In this final section of the Binary Tutorial you will learn how to easily perform binary arithmetic addition, subtraction, multiplication and division by hand.
Binary arithmetic is one of those skills which you probably won't use very often. It can be very useful to know however.
These processes are often stepping stones to more complex processes which can do very powerful things. Fortunately, they are not too difficult so with a bit of practice you'll be off and running in no time.
There are many calculators now which can do binary arithmetic for you. Just about every desktop OS, smart phone and tablet has one built in or one can easily be aquired. It is perfectly fine to use the calculator but we should know how to do it by hand as well. This will give us a much better understanding as to what is actually happening.
That understanding is important in order to understand how certain mechanisms work especially in computing. My recommnedation is to practice on paper by hand but use the calculator to verify your working. Note: For educators, the interactive examples work well for demonstrations on a projector or smart board.
Binary addition is the easiest of the processes to perform. As you'll see with the other operations below, it is essentially the same way you learnt to do addition of decimal numbers by hand probably many years ago in your early school years. The process is actually easier with binary as we only have 2 digits to worry about, 0 and 1. The process is that we line the two numbers up one under the otherthen, starting at the far right, add each column, recording the result and possible carry as we go.
The carry is involved whenever we have a result larger than 1 which is the largest amount we may represent with a single binary digit. Applies to this example and all the examples below. It is possible to add more than 2 binary numbers in one go but it can soon get unweildly managing the carries. My suggestion is that you add the 1st and 2nd numbers together. Then take the result and add the third number to that. Then take the result and add the 4th etc.How To Add Binary Numbers - The Easy Way!

Transaction Failed!The first article discusses binary addition ; the second article discusses binary subtraction ; this article discusses binary multiplication.
The pencil-and-paper method of binary multiplication is just like the pencil-and-paper method of decimal multiplication; the same algorithm applies, except binary numerals are manipulated instead. The way it works out though, binary multiplication is much simpler. The multiplier contains only 0s and 1s, so each multiplication step produces either zeros or a copy of the multiplicand.
To multiply two multiple-digit decimal numbers, you first need to know how to multiply two single-digit decimal numbers. A multiplication problem is written with one number on top, called the multiplicand, and one number on the bottom, called the multiplier. The algorithm has two phases: the multiplication phase, where you produce what are called partial products, and the addition phase, where you add the partial products to get the result.
In the multiplication phase, the digits of the multiplier are stepped through one at a time, from right to left. Each digit of the multiplicand is then multiplied, in turn, by the current multiplier digit; taken together, these single-digit multiplications form a partial product. The answer to each single-digit multiplication comes from the multiplication table. Some of these answers are double-digit numbers, in which case the least significant digit is recorded and the most significant digit is carried over to be added to the result of the next single-digit multiplication.
There are two digits in the multiplier, so there are two partial products: and Each partial product has its own set of carries, which are crossed out before computation of the next partial product. Here is the multiplication phase, broken down into steps:.
When the multiplication phase is done, the partial products are added, and the decimal point is placed appropriately. If there were any minus signs, they would be taken into account at this point as well.
This gives the answer Instead, you just write down 0 when the current digit of the multiplier is 0, and you write down the multiplicand when the current digit of the multiplier is 1. In the introduction, I showed this example: I wrote it as if you followed the decimal algorithm to the letter.Use the following calculators to perform the addition, subtraction, multiplication, or division of two binary values, as well as convert binary values to decimal values, and vice versa.
The binary system is a numerical system that functions virtually identically to the decimal number system that people are likely more familiar with. While the decimal number system uses the number 10 as its base, the binary system uses 2. Furthermore, although the decimal system uses the digits 0 through 9, the binary system uses only 0 and 1, and each digit is referred to as a bit.
Apart from these differences, operations such as addition, subtraction, multiplication, and division are all computed following the same rules as the decimal system.
Almost all modern technology and computers use the binary system due to its ease of implementation in digital circuitry using logic gates. Using a decimal system would require hardware that can detect 10 states for the digits 0 through 9, and is more complicated. While working with binary may initially seem confusing, understanding that each binary place value represents 2 njust as each decimal place represents 10 nshould help clarify.
Take the number 8 for example. In the decimal number system, 8 is positioned in the first decimal place left of the decimal point, signifying the 10 0 place.
Essentially this means:.
My Digital Computation Calculator
In binary, 8 is represented as Reading from right to left, the first 0 represents 2 0the second 2 1the third 2 2and the fourth 2 3 ; just like the decimal system, except with a base of 2 rather than Using 18, or as an example:. Converting from the binary to the decimal system is simpler. Determine all of the place values where 1 occurs, and find the sum of the values. Binary addition follows the same rules as addition in the decimal system except that rather than carrying a 1 over when the values added equal 10, carry over occurs when the result of addition equals 2.
Refer to the example below for clarification. The only real difference between binary and decimal addition is that the value 2 in the binary system is the equivalent of 10 in the decimal system.
Note that the superscripted 1's represent digits that are carried over. The value at the bottom should then be 1 from the carried over 1 rather than 0. This can be observed in the third column from the right in the above example.
