Running the Bases (with TI-RGB Array) for TI-Nspire

Explore base-2, base-10, base-16, and ASCII. Students use a TI-Innovator Hub, TI-RGB Array, and TI-Nspire to display on the array a byte in binary. Strongly aligns with AP Computer Science Principles.

Students use the TI-RGB Array to explore the bases of human-computer interaction

Tool building is an essential aspect of humanity, and the computer is the ultimate modern tool. Humans have big brains, five senses, agile fingers, vocal cords and eat food; computers don’t have or do any of these. Computers have integrated circuits, cameras, microphones, speakers, displays, keyboards, mice, and consume electricity; humans don't have or do any of these. How do our human brains communicate with the computer’s integrated circuits? The computer has two fundamental components, software and hardware. The essential component of hardware is the integrated circuit, while the essential component of the software is logical operations on binary numbers....
