Introduction
Coding with Squishy Circuits?
In these projectss we use an Arduino
(device similar to a small computer)
to measure the resistance of
conductive dough. When we change
the shape of the dough the resistance
also changes. For example, making
the dough a longer, thinner “pipe” for
the electricity to flow, increases the
resistance. We can then cause an
output to change based on the
resistance.
Note: This project is more advanced.
We include some background
information but if you would like more information about something or are confused, we encourage you
to research more about that particular topic or to contact us.
Learning Objectives
1. Students will be able to explain how resistance, voltage, and current are related.
2. Students will explore how resistance is based on physical shape.
3. Students will design and build a circuit to accomplish a desired outcome.
4. Students will be able to modify and implement code on their microprocessors.
