Coding For Disaster Relief

We would like to acknowledge the Traditional Owners of this country, and the custodianship of their elders

past, present, and future.

Acknowledgement of Country

EWB works in partnership with communities in Aus and overseas, helping them to access the

knowledge and appropriate engineering solutions that they need to give them more control of their lives.

Coded Devices Around the World

Example: Farming

Coding Language + Microcomputer + Electronics

Connect your computer to Raspberry Pi: Gently connect the CAT cable (big silver box on the Pi) Then the microUSB cable for power (small silver plug on Pi) Check that small green, red, and two orange lights illuminate on the Raspberry Pi

Open an internet browser (ideally Google Chrome)

Follow the worksheet instructions to learn the fundamentals of most mid to high-level coding languages.

Two things to remember about Python:

It is CaSE SenSItiVE, so copy the worksheet code exactly The code that follows statements & loops (if, while, for, etc) must be indented with the tab key or space bar

Cyclone Aftermath

Rescue Beacon

Beacon Wiring: The Circuit

RESISTOR: gets rid of some power

LED Light: our beacon

WIRE

WIREPower

No Power

6th pin (5 volts

= POWER)

This way round:

Beacon Wiring: Step 1 - Power

Power

Longer leg connected on POWER side (because it’s the positive leg)

Beacon Wiring: Step 2 - Resistor + LED

Power

3rd pin (0 volts

= NO POWER/’GROUND’)

Beacon Wiring: Step 3 - Ground Wire

The Raspberry Pi was designed for students and people who love doing electronics projects at home. They cost around $50 and can be bought online from within Aus.

The breadboard and other cables and electronics can all be bought online or from an electronics store like Jaycar.
