Hi,
I need help understanding how to receive a binary signal from just changing the physical quantities of a computer. I also need help understanding how to convert the google science journal graph to a binary signal.
Thank you,
mar2dina
(For the record: I am using the google science journal to collect the data from my Chromebook. I am only measuring the light, ultrasound, and vibration quantities of my Chromebook so it won't get damaged. For light, I am using the brightness/dimmer buttons on the Chromebook. For ultrasound, I am using a website called https://typatone.com and this is my example https://typatone.com/m/5rxwTtOGHj. Finally, for vibration, I am using the clicking of the keyboard.)

Hi mar2dina,
Using the example of the light level (screen brightness), a binary signal may be defined as follows:
- 1 if screen brightness recorded is greater than X lux
- 0 is less than X lux
Using this, you can generate messages using "binary (1 and 0s)"
Hope this makes sense, please post again if you have any other questions.
Good Luck!
