Great to see that you are now making wonderful videos on the Arduino. One suggestion about the use of different coloured LEDs is to always use bright white LEDs and then colour them with clear acrylic paints such as clear red or clear yellow etc as available from Tamiya. That way, you can always use the same type of resistor.
Thanks for video. As a beginner perspective, I would really like to have some more description on the circuit itself, in order to cmpletely understand what's going on.
There really is not much more to tell. If a pin is configured to be an output (this is done in the software 'setup' section) you can make it HIGH or '1', which means it is 5V and it can send out max 20mA current, or you can make it LOW or '0', which means it is connected to GND and it can absorb max 20mA current. The max 20 mA is enough to power an LED or to drive the signal input of a servo motor. Don't connect heavy loads though or you may blow up your Arduino.

Another great video Rudy... Keep em coming ! Thank you !
These are excellent tutorial videos, well done, keep going!!!
