Programming


Step 1

Click “Advanced” in the drawer to see more choices.

Note: If you met a tip indicating that the codebase will be deleted due to incompatibility, you may continue as the tips say or build a new project in the menu.

Step 2

  • In the “on start” brick, initialize the AI lens and switch the function to the color recognition mode, set the RainbowLED lights connect to P15 port.

  • In the “forever” brick, set to get one image form the AI lens and judge the cards color on the image. If it reconizes the white color, we set the LED headlights and signal lights in white; if we recognizes the blue color, we set the LED headlights and signal lights in blue, by analogy, we programme with green, red, yellow and black card in the same way.
