These are the connections below for our project. The 113KHz mist maker is connected separatelly and it will be always on. You could add a switch for that in order to turn it on and off. Then the rest are all connected to 5V from the buck converter. Make sure you set the converter to 5V. Then connect the data to the LEDs and the input from the PIR module to the Arduino. Connect two 1K resistors to the RX and TX pins of the DFplayer and add the speaker. That's it. Then go below and upload the code.
