In this instructable I describe the first step of my project: an automatic bat scanner and logger connected to the internet cloud.
The first step is to create a bar graph that resets after a while - indicating bat activities. We'll set up the Spark Core to count button presses and display them on the SparkButton LED bar graph.
I assume you are already familiar with the Spark Core, programming Arduino, etc.
This instructable was created during the Instructable build night at the dorkbot meeting Aachen.
What you will need:
- a Spark Core connected to the Spark Cloud
- a Spark Core internet button v1.0
- an account on the Spark web
Not part of this tutorial yet:
- Bat detector itself
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Get the Code and Load It
- open the Spark web IDE
- create a new app "proto1"
- copy the code of the attached file into the web IDE
- add library "SparkButton"
- compile and flash to the Spark Core
Step 2: Test It
- start up the core -> the LED stripe blinks and goes blank again
- now press button 1 a couple of times -> the LED bar lights up more and more
- the bar is cleared every 10 seconds, then you can start over again
