Arduino is an electronics development platform that is open source and also free software. It was created primarily for educational purposes, but has also started to be used on a hobby level. It can also be used for small automation tasks, such as building a smart home. It has become very popular, also due to the fact that it is easy to program, easy to connect to other devices and also because it is available on the market at an affordable price.
Arduino control panels are available in many versions. These types can differ in size, controller type and even memory. They can even differ in the number of inputs and outputs. There are control panels that already have Ethernet, WIFI or Bluetooth built-in.
Arduins can be complemented with Shields, which can be easily added to the main control panels. The Shield allows direct connection to the Internet and has many other advantages. It allows you to control motors or LEDs, but you can also connect it to Bluetooth in addition to the internet by adding a Shield.
The Arduino IDE is a development library where you can add Arduino functions. The Arduino control panel must be connected to the computer primarily via a USB cable. This is used to communicate and program the control panel.
