This robot will be able to move, dance, do funny stuff live when people subscribe to my YouTube chanel. To get the subscriber amount number from my YouTube chanel I made a visual basic aplication that searches for the subscriber number in the webpage. The aplication will than send this number to the COM port via serial strings. The arduino will receive this serial string wich contains the subscriber amount number and will than give command to the servo's. I uploaded the visual basic to my dropbox.

To control the robot I designed a program that gets the subscriber amount from my channel URL and then sends it every second to the COM-port that is connected to the Arduino. The Arduino than reads the received string and reactions accordingly to it. I used a 30A brushed ESC as power supply to get the 5 VDC for the servo's.

Hello there! I'm not sure how you get subscriber count but I suspect you're doing some page scraping. I'd suggest you use the YouTube API to get subscriber counts.

https://www.googleapis.com/youtube/v3/channels?part=statistics&id=<CHANNEL ID HERE>&key=<YOUR API KEY>&fields=items(statistics/subscriberCount)

I think this would also be more up to date.

Cool project! :)

Awesome project!

Using an esp8266/esp32 you can hit the api directly using a library I wrote

Esp32 should have enough pins to run all your servos so you could even replace the nano
