The secret message is:

Code on

The decoded message: Code on
Every row decoded.

Crack it with Python

Python can do the adding for you. int(code, 2) reads a string of 1s and 0s as a binary number. Then chr() turns the number into its character.

secret = [
    "01000011",
    "01101111",
    "01100100",
    "01100101",
    "00100000",
    "01101111",
    "01101110",
]
message = ""
for code in secret:
    number = int(code, 2)
    message = message + chr(number)
print(message)

When you run it, it prints:

Code on
