Jan 19 Class Meeting

What is interactivity?

interaction: what do we want to happen. We want to draw out the amount of time that viewers evalutate/observe the artwork. interaction > technical

libraries: collection of code someone else wrote

GPIO: general purpose input & output

Arduino Uno Pins > our microcontroller

Analog vs. Digital

Analog: spectrum

Digital: either on/off high/low Binary.

DAC: digital to analog converter ADC: analog to digital converter

PWM: pulse width modulation (dimming an LED) > DAC

Input vs. Output

Input	Output
switch	light
sound (mic)	speaker
movement (sensor)	LCD display
light (sensor)	motor
	relay

user friendliness: how much does the viewer need to know

Our microcontroller works on 5V but a lot of other modern microcontrollers work on 3.3V
