+ | ====== Getting started with the LED Ring expansion deck ====== | ||
+ | |||
+ | To get started with the LED Ring expansion deck you can either control the LEDs using the client, or by code. | ||
+ | |||
+ | ==== Using the Client ==== | ||
+ | |||
+ | Start the cfclient | ||
+ | |||
+ | Connect to your Crazyflie and make sure your //LED// tab is visible. | ||
+ | If not, go to View -> Tabs -> LED tab | ||
+ | |||
+ | Now you can address each LED individually and set its RGB color. | ||
+ | |||
+ | ==== Using code ==== | ||
+ | |||
+ | You can easily control the LEDs by using the [[https:// | ||
+ | |||
+ | There' | ||
+ | * basicLedparamSync.py | ||
+ | * basicLedmemSync.py | ||
+ | You can then modify the scripts to your needs by adjusting the color effects, fade effects, RBG values, timings and much more. There' |
