Blynk for Beginners - Example 1: Slider Widget to control LED brightness (PWM output)

Hi Everyone,
In this video, I am going to show a tutorial on to setup a slider widget in blynk app that is use to control a Led brightness that connected to IoT device name NodeMCU ESP8266.
The can led brightness can be controlled by using PWM function and the PWM value is depending on value send by the slider widget.
Blynk app is most popular IoT app that easy to learn. A lot of application can be done by using this Blynk app.
By learning this kind of examples, you will able to develop a simple project that use Blynk app with NodeMCU ESP8266.
I hope you enjoy this video tutorial.

You can also used mosfet/triac (normally its come together with realy) that react as switching to control the bulb intensity/brightness.
