        abstract = {This paper presents the design and implementation of a bidirectional Bluetooth communication system using a Raspberry Pi Pico interfaced with an HC-05 Bluetooth module. The system allows remote control of an LED and the acquisition of analog sensor data via the Pico's ADC. Commands received wirelessly from a mobile device or via a USB-connected laptop (running Thonny) are processed by the Pico, which then sends control signals or sensor data back through the HC-05. Both development (with Thonny) and standalone modes are addressed. Experimental results demonstrate reliable LED control, accurate ADC readings, and system responsiveness under varying conditions. This implementation is useful in IoT applications such as remote monitoring, industrial automation, and smart home solutions.},
