therefor one would want it brighter or dimmer according to the circumstances, maybe i can do an automatic adjustment.

It is intended to use the rotary encoder to set the light intensity of a ledstrip (ws2812b strip) manually, as the apperatus will be used in the dark as in light. The most common are the Arduino Leonardo and the Pro Micro. These boards do not require a separate bridge chip, they can communicate directly over USB. There are some Arduino boards that use microcontrollers with native USB capabilities. The Arduino IDE comes with the drivers for the ATmega16U2 and FT232 so usually you will only have troubles with that if you get one of the clone Arduino boards that use the CH340 (that's the cheapest of the three chips so it's quite common on the cheap clones). Typically the only reason you will need to think about this chip is if you need to install the correct drivers for it in order for your board to be recognized by your computer. The most common are the FTDI FT232 (AKA "FTDI") and the CH340. Other Arduino boards use chips that are specifically designed for this use. The ATmega16U2 is a microcontroller that has native USB capabilities so it can be programmed to act as a serial-USB bridge. The computer then creates a virtual COM port that makes it seem like your board is connected to a serial port on your computer even though it's connected via USB.

For this reason a separate chip is usually added to Arduino boards that acts as a bridge between the serial communication of the ATmega2560 and the USB of your computer. The ATmega2560 is a very nice microcontroller but it doesn't have any USB capabilities. Nowadays we use USB to connect devices to our computers. Serial.prinln()) but most computers these days don't have a true serial port. The ATmega2560 uses serial communication for getting uploaded sketches and communication with the Arduino IDE Serial Monitor (e.g.

all other work will be done in a few months or a year time, when i can research but for now i need the wires to be at the right place. So PLEASE, don't understand this as me being lazy to look it up! i'm just requesting an answer if you are already have the knowledge, i'm not asking others to do my work!! but im in a building stage and this information is needed to place the wires at the right pins, whicnh needs to be done now. I'm looking for some "basic" information on pinout for this particular board that i believe anyone with some basic understanding and experience with arduino and this particular board can answer, that i can not, not at the moment without intensive research, for which i do not have the time at the moment.

please move one, i didn't post this to annoy. To anyone here that is annoyed that i'm asking a question on this board.
