More About eChallenge Puzzles
The eChallengeCoin is an electronic coin with puzzles to solve.
There will be an annual eChallengeCoin.
Every eChallengeCoin has a series of interactive challenges which use a combination of touch sensors (or buttons) and LEDs.
When appropriate, an puzzle may have additional interactive elements such as environmental sensors or sound.
In addition to the interactive challenges, each new eChallengeCoin has 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 serial connection on the eChallengeCoin.
When an eChallengeCoin wakes, the LEDs 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.
The next challenge is shown with a blinking LED.
Touching any sensor (or button) will leave status mode and begin the next unfinished challenge.
The eChallengeCoin will go to sleep after a challenge has been completed or failed.
They also go to sleep if idle for 60 seconds.
The eChallengeCoin also has demos.
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 puzzle.
TIP: Most demos use the wake interface - or all touch sensors at the same time - to immediately put the puzzle back to sleep.
Some interactive challenges are lengthy.
Starting with 2021 eChallenge puzzles, press and hold the wake sequence while an interactive puzzle is running
will immediately finish the puzzle and wait for the user to respond.
IMPORTANT: The serial connection runs at 9600 baud (8N1).
For some reason which escapes logic, the 2020 eChallengeCoin does not work with FTDI's using the FT232 chip. It was the only one to suffer this indignation.
You will find all of the eChallengeCoins and more in the Tindie store.
