the Adventures of Sara Cladlow

I am Sara Cladlow, a social consultant working in Washington, DC. I provide consulting, social training, and event services for both corporate and political clients.

In my first adventure - Sara and The Deleting App - a client asked me to try out their latest software program but it didn't turn out to be as easy as I expected!

You can read my adventure and test your skills by solving the challenges I encounter.

More About ECCs

The 2020 eChallengeCoin is just one of the ECCs. The plan is for at least two ECCs each year. An ECC may not always be a "coin" but it will always be a challenge.

Each ECC has a series of interactive challenges which will use a combination of touch sensors and LEDs. When appropriate, an ECC may have additional interactive elements such as buttons or buzzers. In addition to the interactive challenges, each new ECC will have another story from the Adventures of Sara Cladlow. Within each story, you are tasked with solving the challenges Sara encounters. The story is accessed through the ECC's UART connection.

When an ECC wakes - on the 2020 eChallengeCoin this is done by closing the switch contacts - it will show the current status. The status includes which interactive challenges have been solved, which story challenges have been solved, and if the bonus has been achieved. A solid LED means a challenge is completed and the next challenge is shown with a blinking LED. Touching any sensor will leave the status mode and begin the next unfinished challenge. The ECC will go to sleep after a challenge has been completed or failed. It will also go to sleep if idle for 60 seconds.

The ECCs also have demos. To access a demo, touch opposing sensors while waking the ECC. Once a demo has been activated, it remains active until it is deactivated. To return to the challenges, touch any single sensor while waking the ECC.

TIP: Most demos use all sensors at the same time to immediately put the ECC back to sleep.

IMPORTANT: The UART connection runs at 9600 baud with N81 settings. It works with adapters using the CP210x chip. For some reason which escapes logic, the eChallengeCoin does not work with many of the adapters using the FT231/FT232 chips.
