Story

INTRODUCTION

This project basically aims to show, how to control the intensity on light source using Bolt Wi-Fi module.

So we will go step by step, how to develop this DIY project.

Steps to build the project

Step:-1

· Connect the negative end of Led to ground pin using jumper wire and bread board

· Connect the positive end of Led to 0 GPIO pin using jumper wire and bread board.

Step:-2

Coding part of the program

Go to the Dashboard of the BOLT IOT and the click on product. and then go to add product and the create a product name you like to connect to your Bolt to input devices and you have to collect the data to GPIO then save it.

configure your product.

Step:-3

Connect the Bolt Iot device using USB and power it on.

After execution of the program it will open an HTML page consists of pwm value meter.

If we increase the pwm value the light intensity will be increased.

If we decrease the pwm value the light intensity will be decreased.
