What you need
- TDA7297 Module
- Arduino
- Resistor (10kΩ, 100Ω)
- Jumpers
Steps
- 1. Connect the GND of TDA7297 to the GND of Arduino.
- 2. Connect VCC of TDA7297 to 5V of Arduino.
- 3. Connect IN+ to pin 11 of Arduino.
- 4. Connect IN- to pin 12 of Arduino.
- 5. Connect OUT+ to a speaker.
- 6. Connect OUT- to a speaker.
- 7. Connect the 10kΩ resistor between VCC and IN+.
- 8. Connect the 100Ω resistor between GND and IN-.
Mini project
Create a simple sound system with a speaker and a microphone. In 30 minutes, you can listen to the recorded sound amplified by the microphone.
Common mistakes
- Do not connect VCC to 12V or higher, the module supports only 6V-18V.
- Ensure that the GND is well connected to avoid interference.
- Check that the 10kΩ resistor is correctly installed between VCC and IN+.
- Check the datasheet if you need a bootstrap capacitor.
Recommended accessories
- Speaker
- Microphone
- Bootstrap capacitor (if needed)
Frequently asked questions
