in addition, there is a 3.5mm jack aux input, that can be used to make a wired connection to audio devices, such as laptops, mp3 players, and cd players. a micro usb charging cable is also included for easy charging, and once charged the system will not need to be connected to the mains.īluetooth connectivity allows you to wirelessly stream audio to the speaker from a paired smart device. It is possible to use this children's karaoke system anywhere as a rechargeable battery is built into the speaker. control the volume and echo effect separately to the music to get the right level. Microphone: the handheld microphone included with the sbs50b-plus speaker allows you to sing along to all your favourite songs. The sbs50b-plus karaoke set is a portable bluetooth speaker with dual led light show supplied with a handheld vocal microphone and echo effect, a powerful music system with extra-bass subwoofer - ready to start the party when and wherever you are.ĭual lighting effects: a room filling disco light show is provided by the top-mounted rgb led spinning dome while 16 pulsating dot leds on the front react in time to the music. the sbs bluetooth speaker can be easily powered with usb and charged at the same time, ready for use in the bedroom, garden and more. countless amounts of songs at the touch of a button.įully portable: take the sbs50b-plus speaker anywhere you go, thanks to its built-in rechargeable battery. The value of a long type variable can be a lot greater than that of int and float variables, which is important when clocking time.Bluetooth streaming: stream music from online services such as amazon music, spotify or similar, using your mobile phone, tablet, laptop or even the tv. Unsigned means that the value of the variable can’t be negative: time is always a positive value. unsigned long -datatype: The program clocks time and the time is saved using this datatype.Testing two things is accomplished by using & signs. the LED 1 is on when the reading of the sound sensor is both over 50 and under 150. Using two simultaneous conditions in an if statement( & ): E.g.Using the millis() function, it’s possible to time simultaneous features. millis(): This function clocks time from the start of the program, i.e., returns the number of milliseconds since Arduino began running the current program.All LEDs are controlled individually: each of them is constantly ready to turn on, and their function doesn’t depend on whether the other LEDs are on or not. towards the greatest values provided by the sensorĮach LED is on for a certain amount of time. The range is divided into suitable parts so that each led blinks only during certain amplitudes.įor example, when the reading of the sensor is between: The sound sensor reacts to the amplitude of the sound. Analog sensors are sensitive to interference, and connecting them to a different ground lessens the disturbances.
