ESP8266 Flex Sensor Project

This project demonstrates how to use a flex sensor with an ESP8266 microcontroller to measure flexion and output the angle on the Serial Monitor.

Components Needed

• ESP8266 Microcontroller
• Flex Sensor
• Jumper Wires
• Breadboard (optional)

Circuit Diagram

Circuit Setup

1.Connecting the Flex Sensor to ESP8266:

Flex Sensor Pin: Connect one pin of the flex sensor to the A0 pin on the ESP8266.

Other Flex Sensor Pin: Connect the other pin of the flex sensor to the GND on the ESP8266.

Instructions

1.Code Upload:

Open the Arduino IDE with ESP8266 board support installed.

Install the necessary libraries if required.

Create a new sketch and paste the provided Arduino code.

Connect the ESP8266 to your computer, select the appropriate board and port from the Tools menu.

Upload the code to the ESP8266.

2.Testing:

After uploading the code, open the Serial Monitor.

You should see the raw sensor value and the corresponding angle printed every half second.

Applications

Human-Machine Interface: Use the flex sensor for controlling devices based on hand gestures or movements.

Medical Devices: Integrate into wearable medical devices to monitor joint movements.

Gaming Controllers: Implement in gaming controllers for interactive gaming experiences.

Notes

Sensor Calibration: Calibrate the sensor based on your specific application to ensure accurate angle measurements.

Power Supply: Ensure a stable power supply to the ESP8266 and the flex sensor.
