Arduino Demonstration 2
Using a Pushbutton to Control the LED
We first plugged in all of the necessary components for the
push button demonstration. This included connecting the button and resistor into
the breadboard and then adding the wires to the Arduino, as well as the
breadboard. Next, we plugged in the USB to the Arduino and our computer, after adding the code. We then verified and uploaded our code and pushed the button to
make sure it worked. The red LED that we plugged in turned on when the button
was pushed and turned off when it was released. The code worked and the
demonstration was a success.
We then tried example three in the book: Turning on the LED
when the button is pressed, and keeping it on after it’s released. After uploading
the code and verifying, we tested it. The LED stayed on after the button was
pressed and stayed on until the button was pressed for a second time. Our button
was somewhat loose on the breadboard, so the demonstration only worked
correctly some of the time.
Fading an LED in and
out, like on a sleeping apple computer
First, we built the circuit by re-configuring the wires,
resistor and LED on the breadboard. Next, we created a new sketch on the
computer, putting in the new code for the demonstration. We verified and
uploaded the sketch, and the demonstration worked well. We then wanted to play
with the code and modify the fade time, so we experimented with several
iterations of that. We experimented with making the “fade in” time to be longer, and the “fade out” time to be shorter. The rhythm
of the fade was altered as a result of our experimentation as well.
