An open-source platform known as Arduino may be used to construct electrical projects with the help of user-friendly hardware and software. Each and every Arduino board has a microcontroller as its signature component. On-board microcontrollers have the ability to receive inputs (such as light falling on a sensor or an item being in close proximity to a sensor) and convert them into outputs (drive a motor, ring an alarm, turn on an LED, display information on an LCD). Connecting numerous devices and facilitating the simultaneous flow of data between them is a possibility. You may also monitor them remotely using a simple user interface, which is a possibility.
