17. ELECTRICITY
The flow of electrons through a conductive material
ANALOGY: Water flowing through a hose
Current (amps) = how many electrons are flowing
Voltage (volts) = electrical energy (ie pressure)
Resistance (ohms) = a material's ability to RESIST current

Designed for EMBEDDED applications vs general purpose applications (like a computer) A microcontroller (sometimes abbreviated µC , uC or MCU ) is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output perip herals. Prog ram memory in the form of NOR flash or OTP ROM is also o ften incl uded on chip, as wel l as a typically small amount of RAM . Microcontrollers are designed for embedde d a pplications, in contrast to the microprocessors used in personal computers or oth er general purp ose applications.

Urbbi A service product that fosters delight in urban horticulture through playful interaction. Urbbi is a product-service that helps people take care of the plants in their home and encourages learning in how to grow their own. Whether it be food, herbs or ornamentals, the Urbbi system allows people to keep their plants alive by creating a direct connection between the plants needs and the tools we already use everyday to prioritise and plan our busy lives.
audible color Audible color is an audio-visual instrument. Sound is generated based on color detected by a web cam connected to a computer. Red, green and blue correspond with certain music notes. When the colors are mixed, the resulting secondary colors produce different notes. The size of the colors influences the volume and frequency of the notes played. Color detection and sound generation were created and are controlled using Processing code. https://vimeo.com/43306909#at=0
