From the project

Autonomous obstacle-detecting servo turret using ESP32-WROOM-32E, HC-SR04 ultrasonic sensor, and SG90 servo. Arduino firmware + KiCad schematic.

Autonomous Obstacle-Avoiding Servo Turret — ESP32 A breadboard-based embedded systems project featuring an HC-SR04 ultrasonic sensor mounted on an SG90 servo. The turret sweeps continuously and triggers a visual alert when an obstacle is detected within a configurable threshold distance. --- Hardware Component Part Notes Microcontroller ESP32-WROOM-32E 3.3V GPIO Ultrasonic sensor HC-SR04 Echo pin stepped down via voltage divider Servo SG90 Powered from VIN (5V) Alert Onboard LED (GPIO2) GPIO19 reserved for external buzzer Voltage divider 220Ω + 1kΩ HC-SR04 Echo 5V → 3.3V --- Repo structure

ServoTurret-ESP32: common questions

What microcontroller does the ServoTurret-ESP32 use?

The ServoTurret-ESP32 is built around the ESP32-WROOM-32E, from the ESP32 family.

How many components are on the ServoTurret-ESP32?

5 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the ServoTurret-ESP32 design files?

From the rupeeangad-rutech/ServoTurret-ESP32 repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the ServoTurret-ESP32 design in my own project?

The repository has no license, so all rights stay with rupeeangad-rutech. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ServoTurret-ESP32 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
