Instructor directions are listed below:
1. Show examples of previously created projects (if available) to demonstrate how they are representations of IoT solutions, but not necessarily working models.
- For example, if a group’s goal was to create a drone that picked up trash, the drone would not fly because the Servo is not strong or fast enough for flight. Rather, the group can demonstrate and explain what the drone would do.
2. Remind students of the Servo movements and how it could be incorporated into their design.
- For example, tell students that a standard Servo could be used to make a hand waving motion and a continuous Servo could be used for a car to move around a track.
3. Remind students that their project should have an app component and an Arduino component, so that when the user presses a button on the app, it causes an action for a Servo or LED connected to the Arduino.
4. Have students answer the following questions to strengthen the design of their creation.
- What object(s) will be moving on your project?
- What is the movement of those objects?
- Which Servo(s) is used to get that movement?
- What device(s) does the app control (LED, Standard Servo, Continuous Servo)?
- How will we change our code (in both App Inventor and Arduino) to control the devices to behave how we want?
5. Have students sketch a design of their creation and their app.
At the Thinkabit Lab, we give students 15-20 minutes to design their creation before starting to build. If the teams are ready to start building, feel free to shorten the design time. However, encourage the teams who are still designing to finish their design before starting to build.
