Control Light Intensity using BOLT IOT Module is a simple project that shows the use of WIFI modules for IOT applications. The primary use of this project is to control the intensity of the light that is emitted by the LED. For this, we have a user interface that has access to the BOLT Cloud. In the interface, we can see a Pulse Width Modulation(PWM) value that ranges from 0 to 255, 0 being LED OFF and 255 being LED ON at maximum intensity of brightness. The interface is accessible on the bolt cloud as well as on the the smartphone BOLT application.
With further modification on this project, we can control large lighting systems with just the use of our mobile phones.
Follow the steps below to see how this project is configured.
