Concept:
Although very impractical in its current form, the concept of this switch was to tell the user whether or not their mixing spoon is making contact with the liquid inside the cup when they are mixing it. This switch turns on when the spoon touches the liquid, completing the circuit.
Components:
The following components were used:
- A spoon
- A cup filled with an ionic liquid (water and table salt)
- 4x wires
- 330 Ohm Resistor
- LED light
- Metal straw (to mask the wire)
Demonstration:
Reflection
This was a very fun project, particularly because this was a no-coding project. Therefore, I really had to stretch my imagination and come up with an interesting switch. I think I was inspired to make the mixing switch because I was making coffee for friends that day.
