ESP32 with HC-SR04 Ultrasonic Sensor Circuit Diagram. Now that we have a complete understanding of how the HC-SR04 ultrasonic module works, we have connected all the necessary wires to the ESP32 ...
ESP32 with HC-SR04 Ultrasonic Sensor Wire the HC-SR04 ultrasonic sensor to the ESP32 as shown in the following schematic diagram. We’re connecting the Trig pin to GPIO 2 and the Echo pin to GPIO 1, ...
This project successfully demonstrates how to use an ESP32 to interface with an ultrasonic sensor, read distance measurements, and display the data in real-time on a web page with a hacker-style theme ...
Each project includes a block diagram, a circuit diagram, a program listing, and a program description. The kit includes the following: 1 MakePython ESP32 development board with color LCD; 1 ...
The PMW3901 is a small, low-power optical flow sensor that measures movement by analysing surface patterns. It is widely used in robotics, drones, and automation to estimate position changes without ...
Abstract: This paper presents a sensor-based gaming system that enhances interactivity by leveraging the ESP32 microcontroller and ultrasonic sensors to enable real-time motion-based control.
The system uses ultrasonic sensors and a servo to aid in obstacle detection and an ESP32-CAM to help recognize the object in front of the user. The servo is used in a sweeping motion to achieve a ...
