This is the controller board that holds your code. It contains an on-board LED connected to pin1.
A breakout board that allows you to upload your code from the computer into the microcontroller. If you build your CloudX controller yourself, please note that your controller must be bootloaded before it can work with the softcard. Also know that the CloudX softcard driver must have been installed on your computer before it can work properly.
Called Light Emitting Diode, they are small lights used as indicators in electronics. They are powered with very small amount of current.
It is used to limit the follow of current in a circuit, in this project 330R is used to reduce the current flowing into the LED from the pin1.
For connecting one point to the other on a breadboard.
