How to use waste materials to make something.

Week11 input devices (Apr 13)

Assignment:add a sensor to a microcontroller board that you have designed and read it.

  • Software:
  • AVRStudio 5
    Proteus professional
    EAGLE PCB
    Adobe photoshop
    Fab Modules
    Roland SRM-20
  • Hardware:
  • DS18B20 module


    AVRISP MKII


    Electric iron


    Multimeter


    Copper Clad Laminate

    PC/windows os


  • Process:
  • 1.Design

    Read the data sheet and understood Electrical characteristics for DS18B20 and then designed the system of Temperature Sensor with proteus.

    2.Program

    This process was very important and I had to read data sheet and learned how to use it. As for myself, To learn how to use the Temperature Sensor by program of some examples.

    3.Simulation

    At first times, my simulation was failure, my board couldn't receive the temperature data because my program has some mistakes when I write the code about init DS18B20.

    4.Design and mill the Board

    In this process, I just had a question was that tracing the board was alway not carefully.When I trace the PCB, I was not familiar with arranging the components so that I needed more time to complete it.

    Controller_trace
  • What I have learned
  • 1.Read data sheet is very important for developing.
