A lot of engineers usually face difficulty while handling the connection of their projects, nonetheless, a Bluetooth component can conveniently address this problem. So, automation professionals and IoT fanatics like to construct their jobs based around microcontrollers such as an Arduino or Raspberry Pi. Therefore, these microcontrollers are not able to communicate with various other tools unless we enable them with connectivity. So, this connection is often provided to them via a Bluetooth component. The Bluetooth components are small in size. Thus, we can easily incorporate it in our Arduino and other microcontroller jobs. And as the name suggests, this component communicates with the devices around it by utilizing the Bluetooth innovation. So, it opens an entire brand-new range of possibilities from straightforward information transfer to the remote. MOKO Smart Beacon and also Pin Summary Regular Bluetooth components consist of four standard pins. Therefore, their names as well as respective functions are outlined listed below.
