About the project

This project presents a portable, lightweight tripod platform controlled via BLE designed to pan and tilt using two servo motors. The system enables fine-grained motion control using custom commands sent from a smartphone app. It is built using a Raspberry PiPico, a PCA9685 16-channel servo driver, and an HM-10 Bluetooth module, with power supplied via USB power bank. Commands are issued through the LightBlue BLE interface on iOS, offering low-latency manual control in any environment.

  • ○ Controls logic and BLE UART

    ○ Sends I2C signals to PCA9685

  • ○ Connected via UART (TX/RX @ 3.3V logic)

    ○ Receives BLE commands from smartphone

  • ○ Connected via I2C to Pico (SDA, SCL)

    ○ Provides PWM output to servos

  • ○ One motor for pan (horizontal rotation)

    ○ One motor for tilt (vertical motion)

    ○ Powered from Raspberry Pi Pico as well
