below are the items I used for it:
- Intel Edison
- Stepper Motor
- Timing Belt 3D printer
- Stand for camera
- Cables Tie
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Assemble the Flagpole
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
Step 2: Assemble ULN, Stepper Motor, and Intel Edison
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.
Step 3: 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.
Step 4: Testing
Above is the video that has been fast forwarded because originally it took 2 hours to make this work.
