3. Project Expectations:
See weather data around United Kingdom towns
Run a Python script to connect to weather stations 
Access the external script using enabled remote sensors in the Scratch program
Fetch weather data from specific Weather Stations
Display using Scratch animations

4. Steps Set up Raspberry Pi for first time use
Download software and the Python script
Open Scratch and enable remote sensors
Run the script
(& keep it running, as it will feed data to scratch and will also constantly listen out for broadcasts)
Work on Scratch
Making variables 
Setting variables to specific Weather Station IDs to collect data  
Simultaneously Visualize data being fetched and produced
Display the Animation

5. Step 1: Set up Download RASPBIAN OS image to SD card
Use Win32 Disk Imager to write the image on the SD card
Load the SD card in the slot on the Raspberry Pi
Connect all peripherals (power supply being the last)
Connecting the power supply will automatically power on the device, so make sure all other components are ready.

6. Step 2: Download Python script
Open Terminal (Ctrl, Alt, T)
Type the command:
wget –O interface.py rpf.io/wsd

7. Step 3: Open the Scratch Program
RUN the preloaded Scratch program (in Raspbian OS)
In “sensing blocks” right click “slider sensor value” and enable remote sensor connections
This is to be able to fetch the data from the Python script

8. Step 4: To run the downloaded script
In the Terminal type the command:
python3 interface.py

9. Step 5: Back to Scratch Program
Create a new Variable
Set the variable to a weather
Station ID

10. Step 5 (Continued): Sensors
In “Sensing” blocks use the “Slider Sensor”
block and the pull down menu to select which
sensors to collect data from

11. Step 5 (Cont.) : Use Different Blocks to Display the Data

12. Step 5 (Cont.) : Create & Customize Sprites by uploading images

13. Step 5 (Cont.) : Thermometer Settings
Configure the settings so that the gauge in the thermometer image moves up and down as the weather value is displayed.

14. Step 5 (Cont.) : Arrow Settings
Configure the settings for the arrow sprite that was created to show the speed and direction of the wind.

15. Step 5: Display the animation!
When all blocks are in place
Click the GREEN FLAG to begin the animation!

16. Final Remarks:
Join multiple blocks using variables and the sensors to achieve data output.
Using the Scratch website will cause an “undefined” error in the sensing blocks.
Certain Sensing blocks may only be available in the Scratch Program and not on the web version of Scratch.

17. WEB/IOT
The idea was to send this animation to my website so it can be displayed with my other animation.
Next steps:
Figure out how to have the animation work on a website without using the web version of Scratch
Use a tracker on the website to see how many people watch the animation
