This was accomplished by setting up a Raspberry Pi Pico W as a microcontroller that handles the wireless communication through the Bluetooth Low Energy Protocol. The Pico is connected to an Android phone that sends commands and notifies the Pico while it is connected. The Pico forwards the command to the existing Arduino microcontroller through a state machine kept on the Arduino. The system developed for this paper represents an add-on that successfully carries out the goal of implementing user-friendly wireless control of the existing system. However, further work would be required to create two-way wireless communication that allows the phone app to know whether its command was executed successfully. wireless control android development Bluetooth Low Energy microcontroller development Improving Existing Electrical Systems through Mobile Wireless Communication
