LED and Servo Motor Control Via Bluetooth Based on Android Applications

Abstract

Remote control is needed to control household appliances and office equipment from a distance by turning them on/off. This control is designed using Bluetooth connected to the circuit using an LED for light control indicator and a servo motor circuit for curtain control connected to the Arduino UNO microcontroller as a minimum system. The Arduino microcontroller is used to process command data from the input of the Android-based Bluetooth signal receiver used as the remote-control button to control the LED and rotate servo motor. This hardware is designed using the Arduino UNO module, LED circuit and servo motor. A serial Bluetooth module was used for communication between the hardware and Android smartphones. Having tested the entire tool system and the Android control application, it was found that the device and the application worked well. However, it is only able to receive the data sent from the Android application, but not able to transfer the data from the system to the Android handset.
