Nano Arduino With Neo Pixel Speaker

Arduino Nano and Bluetooth Module Connection:

Connect the TX pin of Arduino Nano to the RX pin of the Bluetooth module.

Connect the RX pin of Arduino Nano to the TX pin of the Bluetooth module.

Connect the 5V pin of Arduino Nano to the VCC pin of the Bluetooth module.

Connect the GND pin of Arduino Nano to the GND pin of the Bluetooth module.

Arduino Nano and Neopixel Ring Connection:

The data input of the Neopixel ring should be connected to a digital pin of Arduino Nano. For example, if you want to use pin D3, connect the data input of the Neopixel ring to pin D3.

Connect the VCC pin of the Neopixel ring to the 5V pin of Arduino Nano.

Connect the GND pin of the Neopixel ring to the GND pin of Arduino Nano.

Arduino Nano and Sound Sensor Module Connection:

Connect the analog output of the sound sensor module to an analog input pin of Arduino Nano. For example, if you want to use pin A0, connect the analog output of the sound sensor to pin A0.

Connect the VCC pin of the sound sensor module to the 5V pin of Arduino Nano.

Connect the GND pin of the sound sensor module to the GND pin of Arduino Nano.

Arduino Nano and Amplifier Board Module Connection:

The speaker output of the amplifier board module should be connected to the positive (+) and negative (-) terminals of the JBL speaker.

Connect the positive (+) terminal of the 18650 battery to the VCC or +VCC pin of the amplifier board module.

Connect the negative (-) terminal of the 18650 battery to the GND pin of the amplifier board module.

Power Connections:

Connect the VCC pin of Arduino Nano to the power output of the power bank charging circuit.

Connect the GND pin of Arduino Nano to the GND connection of the power bank charging circuit.

Connect the power output of the power bank charging circuit to the VCC or +VCC pin of the amplifier board module.

Connect the GND pin of the amplifier board module to the GND connection of the power bank charging circuit.

Additionally, you can add an On/Off button to control the power supply. Connect the On/Off button between the power supply (VCC) of the amplifier board module and the GND connection. This will allow you to control the power to the speaker and LED ring using the On/Off button in your Arduino code.
