● Learn: soldering, wire handling, building robust prototypes, making devices to talk to other devices
● Enrich project functionality
● Encourage future independent exploration
GlossaryArduino: Open-source electronics platform enabling easy-to-use hardware and software, intended for anyone making interactive projects.
Peripheral: A device that is connected (e.g. via Bluetooth) to another device to add functionality. Eg. Mice, keyboards, and speakers are peripherals to computers; and smart watches are peripherals to smartphones.
GPIO: General Purpose Input/Output is a pin on a microprocessor that can function as either an input (e.g. connected to a sensor) or an output (e.g. connected to a display or LED), and may be programmed as such.
IDE: An Integrated Development Environment is software that includes a source code editor, compiler, debugger, and in the case of hardware, a method to program an external processor.
Microcontroller (MCU): Hardware including an integrated circuit with features that enable it to interact with the external world, i.e., sense, collect data, and control “things.”
Shield: Board that can be plugged on top of the Arduino PCB extending its capabilities. The different shields follow the same philosophy as the original toolkit: they are easy to mount, and cheap to produce.
Hardware Prototyping Tools: Microcontrollers
BeagleBoard Raspberry Pi Intel Edison Arduino LittleBits
Make it Wearable! Intended for Makers
We'll cover the electronics, you cover the code.
Open-source computer
Low-cost computer
Getting Started with Arduino● Basics of electricity and
electronics
● Prototyping on a solderless breadboard
● Drawing a schematic diagram
● Talking to a computer--and the cloud--from Arduino
● Building a custom plant-watering system
Why Arduino?Arduino:
● Hardware ecosystem● Component level building● IDE for programming ● Open source● Existing support (forums, shields)
Sample Shields:● Motor drivers● Communication (XBee, BT, WiFi, IR, Ethernet)● Accessories (GPS, Camera, SD reader, MP3 player)● Displays (LCD, LED, audio)● Sensors (pH, weather, voice recognition)
IoT Example: Grape MonitorProblems:
● Lots of factors during the growth of grapes go into the final taste of a wine.
● It is difficult to track exactly what conditions contribute to a particular vintage.
● Too much moisture or too much heat can adversely affect the growth of grapes.
Need:● A way to compare the growing conditions of grapes.● A way to inform us of adverse climate changes so we can take
action to protect our grapes.
Grape Monitor: Data
● Daily temperature swings● Humidity / dryness● Moisture / rain● Sunlight ● Soil pH● Soil mineral content
