1. In your words, what is the binary system?
Binary Numbering ..
2. A byte contains 8 bits of data, What is the highest possible number that can be
represented in a byte? Explain your answer.
3. Write each of the following in a byte using binary:
a. Birth Month (as a number):
b. Birth Day of the month):
I c. Age:
4. A DC motor receives voltage from an 8-bit, 5V Arduino. If the voltage signal ranges from
0-5V, by how much does the voltage increase as the byte increases by 1? (HINT: Think
about the maximum number in a byte and the maximum voltage)
5. For the DC motor in question 4, if you want to send 3V to the motor, then to what value
should you set the Arduino Pin?
6. Write the answer from question 5 as a byte in binary.
7. Determine how many bits the Temperature sensor sends. (HINTA find the maximum
voltage sent by the sensor and find the value read by the Arduino at that voltage.)
