One of the advantages of the arduino platform is that it allows one to store and access data from an online server. Using the arduino redback - yellowjacket compatible I am going to show you how to access data from an online server.
Step 1: Setup
What you need for this project is:
1. arduino redback
2. ft232rl breakout board
Step 2: Connection
Mount the arduino redback onto the ft232rl breakout board as shown in the diagram. Ensure that the DTR pins match.
Step 3: Code.
The arduino code is attached below
Step 4: Process
The arduino redback sends a get request (www.kisese.byethost7.com/kura/results_b.txt) to the server. The server then returns the data contained in the text file results_b.txt. As simple as that.
Step 5: Results
Data from the server is printed onto the serial monitor, every 10 seconds as shown in the image. You can edit the code to change the time interval and the get request too. Therefore, feel free to play around with the code. Meanwhile, you can view the full tutorial here.
