Description:
RGB is LED Unit include 3 individual LEDs. It is also one of the Unit from M5GO Kit. Each one can display anycolor based on RGB value. One feature of this Unit is extension, which means you can have mutiple of them wired together.
This is a very useful piece on STEM class, students can program it to realize some of cool applications, for example a traffic light.
Product Features:
- Program Platform: for , UIFlow(Blockly, Python)
- Two Le go-compatible holes
Package Include:
- 3 x RGB Unit
- 3 x Grove Cable
EasyLoader:
1.EasyLoader is a simple and fast program burner, and each product page has a product-related case program for EasyLoader.
2.After downloading the software, double-click to run the application, connect the M5 device to the computer via the data cable, select the port parameters, and click "Burn" to start burning.
3.The CP210X (USB driver) needs to be installed before the EasyLoader is burned. Click here to view the driver installation tutorial Example:
