This course is at the boundary of code and physical objects. While we access the GPIOs of our reTerminals using filesystems and code, ultimately the digital signals are being delivered with electricity along conductive physical components.
Signals: Digital and Analog
- 16 February 2026
Modern computer science depends on electricity to physicially store and transfer information. In this program, you have learned about the binary representation of information, which depends upon the electrical transistor to store the “values” 0 and 1.
