kidsbits blocks coding knock 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 wiring and damage.
The knock sensor is mainly composed of SW-280 vibration switch, which is an inductive proximity switch.
It is an electronic switch that transmits the sensing result to the circuit device and induces the circuit to start working when the vibration force is induced.
You can make full use of it with creative thinking, like electronic drum, and so on.

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.
Click on the digital read block of keyes_kidsbits, you can directly drag out the corresponding module to use.
5. Test Code
Open or directly drag the Mixly code of touch sensor to the Mixly window.
Check the C language code:
6. Test Result
Hook it up and upload the code success, knock the sensor, the D13 indicator on the control board will light up for one second, then turn off.
