  2. Here's a way to convert binary numbers to ASCII characters that is often simple enough to do in your head. 1 - Convert every 4 binary digits into one hex digit. Here's a binary to hex conversion chart: 0001 = 1. 0010 = 2. 0011 = 3. 0100 = 4. 0101 = 5. 0110 = 6.

  3. Binary to String/Text in Python - Stack Overflow

    # Simple not elegant, used for a CTF challenge, did the trick # Input of Binary, Seperated in Bytes binary = "01000011 01010100 01000110 01111011 01000010 01101001 01110100 01011111 01000110 01101100 01101001 01110000 01110000 01101001 01101110 01111101" # Add each item to a list at spaces binlist = binary.split(" ") # List to Hold Characters chrlist = [] # Loop to convert for i in binlist ...

  4. There are other character sets, and code pages that represent different letter, numbers, non-printable and accented letters. It's entirely possible that the binary 01000001 could be a lower case z with a tilde over the top in a different character set. 'computers' don't know (or care) what a particular binary representation means to humans.

  5. If you then need to format this in binary, the string.format() method will do the job. a = "test". print(' '.join(format(ord(x), 'b') for x in a)) (Thanks to Ashwini Chaudhary for posting that code snippet.) While the above code works in Python 3, this matter gets more complicated if you're assuming any encoding other than UTF-8.

  6. Arduino 8x8 led matrix letters - Stack Overflow

    stackoverflow.com/questions/55090907

    To accomplish this, you need to loop through each row and each column, turning on the needed leds for a brief period of time and then turn them off again; doing this fast enough makes it appear as if all of the leds are on at the same time. /*. Name: Arduino8x8MatrixStackOverflow.ino.

  7. 5. A binary file appears as gibberish because the data in it is designed for the machine to read and not for humans. Sadly, some of us get used to interpreting gibberish - albeit with somewhat specialized tools to help see the data better - but most people should not need to know.

  8. Computers doesn't actually translate anything to binary, it's all binary from the start, and the computer never knows anything other than binary. The character A stored in memory would be 01000001 , and the computer doesn't see that as anything but a binary number.

  9. Use toString(2) to convert to a binary string. For example: var input = document.getElementById("inputDecimal").value; document.getElementById("outputBinary").value = parseInt(input).toString(2); or parseInt(input,10) if you know the input should be decimal. Otherwise input of "0x42" will be parsed as hex rather than decimal.

  10. For example, character A is 1000001 (0x41) and character a is 1100001 (0x61).The difference is in bit 6, which is 0 in uppercase letters and 1 in lowercase letters. If we know the code for one case, we can easily find the code for the other by adding or subtracting 32 in decimal, or we can just flip the sixth bit.

  11. I made a recursive function which takes a binary code and is supposed to convert to the letters "A", "T", "C" and "G". Then in this, it's supposed to assign that binary code to the corresponding letters below, but it just doesn't move past the first letter.
