1. Description

kidsbits blocks coding I2C 4-digit LED segment display module 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 module integrates a 4-digit LED segment display.

To save the IO ports of microcontroller, the module uses the TM1650 chip to drive the 4-digit LED segment display. It uses the I2C communication with microcontrollers.

Follow the instruction use mentioned below to get further knowledge of this module.

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. Upload Code

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

You can click the Code to check the C language.

7. Test Result

Hook it up and upload the code success, you should see the 4-digit LED segment show the number“12.34”for one second then go out for one second, repeatedly and circularly.
