Tutorial: How to use LM1036 + NE5532 Tone Board

The LM1036 + NE5532 tone board is ideal for creating a frequency tone generator on Arduino. Suitable for beginners and intermediates.

What you need

• Arduino
• Power supply cable
• 10kΩ resistor
• Microphone or sound source
• Emergency shutdown

Steps

1. 1. Connect the Arduino to the power supply (5V).
2. 2. Connect the VCC pin of the tone board to the 5V of the Arduino.
3. 3. Connect GND of the tone board to GND of the Arduino.
4. 4. Connect the IN pin to pin 11 of the Arduino (or any other digital pin).
5. 5. Connect the OUT pin to an available digital pin.
6. 6. Connect a 10kΩ resistor between the VOLUME pin and GND.
7. 7. Connect the GND pin of the board to GND of the Arduino.
8. 8. Test the tone generator with a microphone or sound source.

Mini project

Create a simple frequency tone generator with a microphone and an LCD display to show the frequency.

Common mistakes

• Omitting the GND connection can cause malfunctioning issues.
• Connecting the VCC pin outside of the power supply can damage the board.
• Using a resistor other than 10kΩ can affect the sensitivity of the tone generator.
• Setting the wrong digital pin can render the tone generator non-functional.

Recommended accessories

• LCD Display
• Microphone
• 10kΩ Resistor
• Test Lead

Frequently asked questions

Can I use any resistor for the VOLUME?
Check the datasheet, but 10kΩ is recommended.

Does the toner work with any sound source?
Yes, but low impedance microphones work better.

Why doesn’t the toner respond?
Check the connections and the pin being used.

Can I use the board with another microcontroller?
Check compatibility with the microcontroller’s datasheet.
