1. Description

kidsbits blocks coding crash 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 crash sensor outputs a button signal, or a digital voltage signal. When the sensor crashes an obstacle and the switch is turned on, the signal end outputs a LOW level signal. When the switch is released, the signal end outputs HIGH level.

This sensor can be used as limit switch for 3D printers.

2. Technical Parameters

  • Interface: EASY plug
  • Operating voltage: DC 5V
  • Output signal: digital 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.

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, if the shrapnel switch of crash sensor is pressed, both SIG LED on the crash sensor and D13 indicator are turned on.

Once release the switch, both LEDs are turned off.
