Task 5 from Spain - Light metter with LDR sensor and 7 segments display

  • Light metter with LDR sensor and 7 segments display

     

    Try to plan your work with any mate in class or from eTwinning by chatroom and forums, you can work in pairs.  The App must be related with the eTwinning project "Scratch and Arduino from east to west", contents, media, intercurtural information between countries, etc.

     

    We will use the following examples to carry out our exercise:

    https://www.arduino.cc/en/Tutorial/Calibration

    http://www.geekfactory.mx/tutoriales/tutoriales-arduino/tutorial-arduino-con-fotoresistencia-ldr/

     

    Use your arduino kit to build a light meter using an LDR resistor as an analog input and a 7 segment display for digital output, indicating the lumensity value in a range of 0 to 9. For this you use part of the Arduino example code Calibration, LDR sensor and 7-segment display, all of these examples are in topic 11 in moodle.  Add a red LED to turn it on if it exceeds the value 5 on the display.  Physically implement the project with the Arduino board, the protoboard, Leds, cables, etc. And make it works.

     

    1. Perform the program in the Arduino IDE. Discuss each line of code you use. Deliver the Arduino program to its native extension.
    2. Make a video with iMovie with the specifications below. Delivery URL of the video. In the video description delivers the text of the complete program code.

    Video specifications:

     

    1. Duration of less than 1 minute.
    2. Start with title and description.
    3. Divided screen, left video of hardware in operation, and simultaneously to right monitor quicktime recording of arduino series with outputs programmed with order Serial.println.
    4. Final with credits (author, date, course and school).
    5. Music with copyleft or in default indicating author and "disclaimer".
    6. Video or letters in English, and logos of eTwinning and the project "Scratch and Arduino from east to west" must be in the video.

    Publish your work in the forum.  You can try downloading your classmates ones if you have previously uploaded it to the forum on Twinspace.  Use the Forums to show your work using the URL of your video in youtube.
