1. Description

kidsbits blocks coding analog sound sensor is fully compatible with kidsbits control board and Lego building blocks.
You can easily connect it to kidsbits control board for communication using an RJ11 cable without worrying about wrong connection and damage.

The sound sensor is typically used in detecting the loudness in ambient environment.
The kidsbits sound sensor has a signal terminal that is an analog output, and is a real-time output of the voltage signal of the microphone. The signal gain can be adjusted by the potentiometer.
Turning the potentiometer clockwise is to reduce the signal gain; while turning the potentiometer counterclockwise is to increase the signal gain.

You can use the sound sensor to make interactive circuits such as a voice-operated switch.

2. Technical Parameters

  • Interface: EASY plug
  • Operating voltage: DC 5V
  • Operating current:<10mA
  • Output signal: analog signal

4. Import kidsbits library

Begin with the Mixly blocks coding, you should first import the corresponding kidsbits library for those sensor modules.
Connect the control board to your computer using a USB cable.

Then open the Mixly blocks software 0.998, set the board to UNO R3, select your correct COM port. On the upper right corner you can switch the language.

After that, click Import, import the keyes-kidsbits library. Shown below.

If import custom library successfully, you should see the sensor module library shown below.

Click on the display screen block of keyes_kidsbits, you can directly use the corresponding module. Shown below.

5. Test Code

Open the code folder we provided, or you are able to directly drag the code to Mixly window.

You can click the Code to check the C language.

6. Test Result

Hook it up and upload the code success, open the monitor and set the baud rate to 9600. It will display the analog value of current sound volume.

When the analog value is greater than or equal to 100, the D13 indicator on the control box will flash on; otherwise, the led will be off.
