Controlling output devices (with APIs)

Hope you have completed the steps given under Controlling output devices (Glowing an LED).

If yes then head over to your computer and open a web browser, we shall craft a URL that will turn on the LED.

Here are few points about this tutorial:

  • The URL connects to the Bolt IoT cloud
  • It uses your API key and device ID, then we pass a command to turn ON pin 0.
  • Command structure:
    • This command is called ‘digitalWrite’
    • We pass the command the pin number/name
    • Then the state HIGH, which means ‘on’ or LOW which means ‘off’.

So here is the URL: API KEY/digitalWrite?pin=0&state=HIGH&deviceName=YOUR BOLT DEVICE ID

Type this URL, remembering to change the API and Bolt Device ID and press Enter.

Your LED will come to life! 💡 That was simple!

Now to turn it off, just change the HIGH in the URL to LOW.
