CIRCUIT 1:
In this circuit, the LED will fade and shine repeatedly.
CIRCUIT 2:
In this circuit, the buzzer will make some music.
CIRCUIT 3:
The function of this circuit is to compete the clicking speed between two people, and whoever has clicked their button ten times the fastest wins!
When I was building the circuit, I didn’t do a good planning beforehand, and as a result, the space ran out as I was finishing the circuit. As you can see from the picture, the second push button was squeezed onto the board. And the whole circuit seemed quite messy.
My group used two ways to play the game, one was the original pushbuttons, the other was the paddles.
The circuit looks like this:
Additional questions:
- Another kind of creative button we can use is a kind that can measure the speed of eye blink. Whoever has blinked their eyes ten times the fastest wins. And according to the article Physical Computing, Introduction Chapter, this button is more interactive for it engages the eyelids rather than only fingers, puting more senses to use.
- The 10k resistor provides a connection to Ground, and to ensure we always read LOW when the button is not pressed.
- The Arduino way mentioned in the article includes protopying and tinkering, which mean that one can come up with an amazing design by combining two existing devices or reusing existing technology. Here’s an example of creating in the Arduino way:
In this case, the designer creates something by combining the existing technology(a camera and a projector), so that it can be used to detect an object and project related content on or around it. And just like that, a new device was born in the Arduino way.
