Controlling the intensity of led using IOT BOLT & SmartPhone

Things used in this project

Hardware components

Jumper wires (generic)

LED (generic)

Bolt IoT Bolt WiFi Module

Breadboard (generic)

Software apps and online services

Bolt IoT Android App

Bolt IoT Bolt Cloud

Story

The System is such a useful IoT tool which helps to calculate the actual intensity of light and convert it in a manner so that the intensity of LED can be set according to the required intensity.

We can control led through internet.There is no need of switch board and we can acces even from some distance.

So without wasting any time let's move to the further steps to create such a device for ourselves.

The Bolt Iot circuit for controlling intensity of light

So here is the small video of my project-

Step 1:

The most first thing is connection. So I"ll tell you step by step how to do connections.

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

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

Step 2: A unique way of Getting the Bolt API Key and Device ID

Login to www.cloud.boltiot.com go to dashboard and then click API there you will get a option called generate key copy the 20 digit API key.

Step 3: 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 4:

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

Here is the image of screen where we can control the intensity of light through smartphone

From here we can increase or decrease the intensity of light
