Interactivity

Started class by discussing interactivity. The main takeaway was that it is important to step away from basic 1-1 call and response. Interctivity, as it pertains to this class, needs to move beyond the basic action of pressing a button and having a sound play or a light turn on. Truly interactive works will consist of multiple parts that function independently and interact with one another.

New Terms

GPIO - General Purpose Input/Output - signal pin on cirrcut board, can be used programmed for input, output, or both.

IDE - Integrated Development Environment - Comprehensive software development toolset - VSC, Arduino, etc.

PWM - Pulse Width Modulation - reduces average power by subdividing signal into multiple parts.

Analog vs Digital

Analog

• Continuous signal, any amplitude

Digital

• Binary signal
• HIGH/LOW, T/F, On/Off

Input vs Output

Input

• Microphonee
• Light Sensor
• Switch

Output

• Speaker
• Motor
• Light
• Display
