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.
5.Solder
6.Flash
7.Test
DS18B20.c
Controller.brd
Controller.sch
Controller_outline
Controller_trace
1.Read data sheet is very important for developing.
2.How to use Temperature sensor to do something .
