This project demonstrates how to build a signal generator using the ESP32 microcontroller and the AD9833 DDS (Direct Digital Synthesis) Module. The ESP32 hosts a webpage that allows users to set the frequency and waveform type (square, sine, triangle) for signal generation.
- Generate precise waveforms: Square, Sine, and Triangle.
- Set the desired frequency via a hosted webpage.
- Easy-to-use interface for waveform selection and frequency input.
- Suitable for IoT applications, electronic experiments, and educational purposes.
- ESP32 Dev Module
- AD9833 DDS Module
- Resistors and capacitors as per circuit requirements
- 2x 9V Battery
- 0.96 inch OLED Display
- LM324 OP-Amp
- Clone or download the repository to your local machine.
- Upload the provided code to your ESP32 board using the Arduino IDE.
- Connect the AD9833 DDS Module to the ESP32 as per the circuit diagram.
- Power on the ESP32 board and access the hosted webpage to set frequency and waveform parameters.
- Power on the ESP32 board and ensure it is connected to your local network.
- Open a web browser on your computer or mobile device.
- Enter the IP address of the ESP32 in the browser's address bar (e.g., http://192.168.1.100).
- The hosted webpage will appear, allowing you to select the waveform type and enter the desired frequency.
- Click the "Set Frequency" button to apply the settings.
- Monitor the waveform output using an oscilloscope or suitable visualization tool.
- If you encounter issues with the webpage not loading or settings not being applied, check the network connection and ensure the ESP32 is running the correct firmware.
