Application Note 106 provides a walkthrough on how to build a basic application to control the brightness and ON/OFF status of LEDs connected to a Samsung ARTIK 710 using Qt software.
The application implements slider bar and toggle button UIs to enable users to control the status of each LED. While the slider bar changes the duty cycle of the PWM port to affect the brightness of the LED, the toggle button will change the GPIO value to turn the LED on and off. Alternatively, the onboard LED located on the ARTIK 710’s main board may be used to verify the status.
To successfully complete this application, you will need a Samsung ARTIK 710 module, an interface board, a touchscreen, and two LEDs.
