What is USB Arduino®?
Universal serial bus (USB) Arduino® is any board Arduino®, which uses USB as the primary interface. Arduino® is a platform with an open source microcontroller and electronics. Virtually every desktop and laptop computer comes with USB ports, which means that USB can connect with almost any computer. There are several varieties of these boards in production.
The purpose of the USB Arduino® interface is to allow the computer to be reprogrammed or provided by the device. For example, a programmer using a short -range radio can be wirelessly connected to a system that controls the lights in his house. After connecting, the programmer could tell the program to change the lighting modes and set all lights to the levels suitable for dinner if the program contains dinner mode. If the program does not include dinner mode, it could use the same interface to record the modified version of the program into the device.
most Arduino® devices do not use a separate computer interface to access and program. If the computer breaks with an invention via USB connection, it is unlikely that it has any other mechanism. These devices can receive input from other sources such as sensors and switches. A device used to control lighting can also take instructions from a dial on a wall or from a sensor of light or movement. Sensors and switches, even if they are technically interface, are much more limited than USB or other computer interfaces and cannot be used to reprogram the device.
There are several advantages of using USB Arduino® over other microcontroller interfaces. In addition to the normal USB interface, it is also cheap and fast. It requires very little energy for operation and USB connection can be used to charge the device when connected. The USB cables are also much easier for wires and repairs than wireless data transmission methods or older serial cables.
the main limitationBy using the USB Arduino®, it must be physically connected to the computer to connect it, so that several wireless computer interfaces have been created for the platform. WiFi® boards can easily connect to computers if the wireless router is present. Xbee® boards operate more independently and at longer distances. Bluetooth® boards still have a limited range, but have another advantage that they are able to connect with smartphones. Despite some limits, USB Arduino® boards are cheaper and more energy efficient than wireless alternatives.
