Tutorial: How to use TDA7293 Audio Amplifier

The TDA7293 audio amplifier module is ideal for DIY projects such as portable speakers or home theater systems. This tutorial will guide you through the installation and configuration of the module.

What you need

• Arduino Uno
• Breadboard
• Jumper Connections
• Speaker
• 12V-32V Power Supply

Steps

1. Connect the TDA7293 module to the breadboard and ensure it is positioned correctly.
2. Connect the power supply to the TDA7293 board. Check the power supply voltage (12V-32V) on the datasheet.
3. Connect the audio pins of the module to the desired microphone or audio source.
4. Connect the breadboard to the Arduino Uno using jumper connections for the necessary control signals.
5. Check all connections and ensure there are no short circuits.
6. Upload the Arduino sketch to the microcontroller.
7. Test the amplifier with an audio signal. Adjust the volume to the desired level.
8. If everything works correctly, proceed with the creation of your project.

Example code

void setup() {
pinMode(A0, OUTPUT);
}

void loop() {
analogWrite(A0, 128); // Imposta il volume a metà.
}

Mini project
