Configure LEDs Ports

This guide provides step-by-step instructions to configure three ports as outputs to control three LEDs (green, yellow, and red). Follow the steps below to complete the configuration process:

Step 1: Turn on your system​

Turn on your board by plugging it into a power source using a USB cable or a DC adapter. Open your Tamra app and access your board from the app

tip
  • Sometimes you may need to wait a few seconds till your board and your Tamra app connect to cloud.
  • Built-in LED flickers until the board connects to the Tamra Cloud.
  • you can check the connection led in your app to make sure your Tamra app connects to the Tamra cloud.
  • It's a best practice to restart Tamra application especially when it shows a black screen.

tip

Always try to keep the built-in LED for testing the connection states of your board, your application, or your system generally. So, keep the configuration of port D13 as an output.

Step 6: Save Settings​

Click on the 'Save Settings' button at the end of this page.
