Cosmo is a STEM educational robot based on Arduino .
Product Link(https://www.dfrobot.com/)
- This library provides the implementation methods for all functions of Cosmo, such as controlling motors, receiving Bluetooth commands, controlling WS2812, controlling RGB, obtaining light intensity, checking battery level, retrieving infrared sensor information, and gathering information from patrol sensor, among others.
Here's one way to use this library:
- First download the library file, paste it into the \Arduino\libraries directory, then open the examples folder and run the demo inside that folder.
