Infrared Remote Control on StemBit - micro:bit Learning Kit

Note：

• You must face the Infrared Remote Controller towards the micro:bit Expansion Board Infrared receiver.
• If you want to use it as normal then you’ve to take down the plastic piece which is in bottom of the Infrared remote Controller.
• The infrared light emitted by the infrared remote controller and the infrared receiver is invisible to the human eye. It can be seen under the camera without filtering infrared light.

Step 1

First you need the download the program of Stembit (https://github.com/sbcshop/pxt-stembit-remote), Then open the power button of IR Car and press the button of the infrared remote controller. The IR Car will have respond by action.

StemBit Programming methods

Online programming:

First, we need to connect the micro:bit to the computer by USB data cable, the computer will pop up a USB flash drive. Then, click on the URL in the USB flash drive: http://microbit.org/ to enter the edit process interface, click to 【Extensions】, and copy the package URL: https://github.com/sbcshop/pxt-stembit to the input field, and you can use the building blocks of the StemBit software package.

Offline programming:

Click to 【Extension】 and copy the package URL: https://github.com/sbcshop/pxt-stembit to the input field and you can use the building blocks of the StemBit software package.

Step 3

Studying blocks

When the power button on the remote controller is pressed, the code inside will be executed, and the button can be customised.

Set the infrared remote control receiving pin. In this experiment, the receiving pin is P8, so you must select P8, Otherwise you will not receive the signal.

The above is the program for this StemBit IR Car. After writing, we need to download it to the micro:bit board.
