Today we have four goals:
- Scavenger hunt: use port view on the sensors to measure light.
- Use data logging on the robots to measure light
- Upload a Word Document with our results to Fronter
- Building Challenge: TBA
Using port view:
Here are some instructions for using port view (see half way down the page): link
You first skills task:
Take the pencil, paper, robot and a light sensor on a scavenger hunt and find locations with 10 different AMBIENT light levels (not reflected or colour). Set the light sensor to ambient light. You have 10 minutes. Return to class, put the information into a Word document and upload it to Fronter. link
If you have extra time, try reflected light.
Today’s mini-challenge: F1 race course. 1 point, cross the first line; 2 points, cross the second line; three points, stop exactly on the second line.
Your second skills task:
Open up EV3 Mindstorms program. Start a new EXPERIMENT, not a new program. Choose how long to record for. Choose what mode your light sensor is in (ambient). Upload your experiment to the brick. Disconnect and the use the brick screen to find your experiment (it should be on the second tab, under ‘project’, unless you renamed your project). Press go, and take your robot on a journey. Bring the robot back, plug it in, and then go to the ‘Tools’ menu and choose ‘data log file manager’. Down load your data. Now take a screen capture by pressing the ‘Print Screen’ button on your keyboard. Open up a Word document and press ‘paste’. For a B on this task, add a label below the screen capture: list the significant way points on your journey: in class, in hall, near office, outside door, full sunlight. For an A on this task, right click on the screen capture and add callouts to label the screen capture. Here is how: link
When we have finished the second skills task, we move on to today’s building challenge!
(Not announced until after skills tasks: One motor challenge. 50 cm, 30 seconds, fewest parts)
