DIY Twitter Flagpole

below are the items I used for it:

• Intel Edison
  
• ULN2803a
• Stepper Motor
• Timing Belt 3D printer
• Stand for camera
• Broomstick
• Cables Tie

Followed by attaching the camera stand and stepper motor on the broomstick using a cable tie. Making sure the timing belt is not too tight

Follow the scheme. Next we will turn the pulley. Here is the code I wrote in Python. countFlagSteps.py

Just download the code and execute it in terminal just simply "python countFlagSteps.py"

When the flag has reached the top, press ‘Ctrl + C’ to interrupt the program, then the program will output how many rounds it takes to reach the top. When all the steps is considered a success, now we will connect to twitter.

Before starting it we better make the twitter application first. We will utilise the API Streaming to get the number of tweets in real-time. Here is the code. countTweets.py and also we have to prepare token_key.txt from twitter

Now lets test the code we made is working or not

Run the code "python countTweets.py -oauth token_key.txt [word_tracking]". In picture I wanna flag will go up triggered by word "garudaku" from public twitter timeline. So I just type "python countTweets.py -oauth token_key.txt garudaku"

if somebody tweet "garudaku" it will print how much tweet and the flag will go up.

Above is the video that has been fast forwarded because originally it took 2 hours to make this work.
