Flux AI: Fritzing

To create the circuit diagram for your project, you can use Fritzing, which supports visualizing components like the ESP32, MPU6050, and other peripherals. Here's an overview of the connections and components for your motion-sensor-based alert system: Connections Overview 1. ESP32 Microcontroller: Power Supply: Connect the 3.7V Li-ion battery to a voltage regulator (e.g., AMS1117) to provide a stable 3.3V to the ESP32's Vin and GND pins. MPU6050 Motion Sensor: Use the I2C protocol: SCL → GPIO22 SDA → GPIO21 VCC → 3.3V GND → GND 2. Bluetooth (if external): TX (HC-05) → RX (GPIO16 on ESP32) RX (HC-05) → TX (GPIO17 on ESP32) VCC → 3.3V GND → GND 3. Buzzer: Positive terminal → GPIO25 Negative terminal → GND 4. Optional LEDs: Use 330Ω resistors with LEDs for status indicators: Power LED: GPIO26 Alert LED: GPIO27 Tools for Circuit Design Use Fritzing to design the circuit visually. You can find prebuilt parts libraries for ESP32, MPU6050, and other components on Fritzing forums or similar resources like this example project【12】. You can also adapt existing tutorials like the MPU6050 interfacing guides from Adafruit to refine connections【10】【11】. Circuit Example A similar setup combines the ESP32 with the MPU6050 for motion tracking. The Fritzing diagram for a comparable project shows how the accelerometer connects to the microcontroller, with power supplied through a regulated voltage source. You can find a detailed Fritzing-compatible file or create your own by referencing tutorials from sources like Microcontrollers Lab【10】【11】. If you'd like, I can help with coding details or further assist in refining the schematic!
