Stopwatch, Fun with Arduino
Electronics Prototype, HCID 521 Prototyping Studio, t University of Washington
Know about Arduino
It was the first time for me to play with electronics. Really excited and had lots of fun! Though, I was also a bit confused about the fundamental theory behind the magic “blink”, and it seemed that I need to pick up the theories of Physics I learned in my high school. I came back to online tutorials and books in Studio, to familiar with the operating principles of Arduino, as well as try to get familiar with Arduino Budget Pack.
When I was searching tutorials and example of Arduino projects, I found an app — Fritzing, it is used to visualize the connections between the Arduino and the components on the breadboard.
After the learning trip, I started to create my own learning goals. Without any software or hardware development, and electronic engineering background, I decided to follow tutorials and try to create small projects.
I found an Arduino Workshop Tutorial, looking through the ten examples, and found out they are really interesting projects to try on.
Play with Arduino
Firstly, I tried the Arduino Texter, and failed, then I realized, yes, I did not have the GMS shield. I could be able to make phone calls and text messages if I had one. Then, I decided to work on the Stopwatch, which I had enough materials.
First, I created a simple pressButton.
Then, I added another button, and created a stopwatch.
Press button1 to start, and press button2 to stop. The serial monitor will show you the time elapsing.
Furthermore, I was thinking about if I could do something more to make it more interesting and useful. Yes, I added a LED, so that I can set the time. For example, I set 10s. If the elapsed time is greater than 10s, then the LED will blink. It works!
Would explore more and deeper if I had more time indeed! Fun Arduino!
