Story

1. Introduction: This project has mainly two purpose i.e. playing the buzzer in high speed (here high speed means normal speed of buzzer ) and playing the buzzer in low speed (here low speed means turn off the buzzer). Nowadays, When irregular incidents happen in our homes, industry, colleges, schools, and many places, we need a manually control alarm to make people aware. so I decide to make it. Here I wrote software code in bolt cloud and give warning via buzzer.

2. Demonstration:

3. Control buzzer: (working principle)

3.1 Hardware connections:

step 1. first of all I insert the negative leg(smaller pin of buzzer) of buzzer in the ground pin of bolt via male-female wire.

step 2. Then I insert positive leg of buzzer (bigger pin of buzzer) insert in 0 pin of bolt via male-female wire.

Now circuit connection is complete.

step 3. Then I power on the device and connect with internet via mobile hotspot using bolt iot Androld app.

Gocloud.boltiot.com and I check whether device is online or not.

3.2 Make new product and configuration them:

Now click on product icon given in cloud.boltiot.com, fill some information and click on done. screenshot is below

After that click on configuration icon given in top bar and fill the required information for hardware.

Next I go for code section and write html code.

3.3 code:

After that click on save icon.

Now I click on view device icon given in top bar.

3.4 Turning on and off the buzzer:

Then I see below page.

When I click on high button then the buzzer is turn on and if I click on low button then the buzzer is turn off.

4. code : I write code and code explanation in code section.

Code

control_buzzer

control_buzzer

HTML

EXPLANATION OF CODE ::: first of all I write Doctype(in line 1) then I write opening html tag.(in line 2) in html tag I write opening head tag(in line 3) ,in head tag I write title(in line 4) and a java script file which include some pre define function like digitalread.(in line 5). Then i write opening script tag.(in line 6) Then I set the Api key and device name (in line 7) , close the script tag(in line 8) ,close the head tag(in line 9) and start the body tag(in line 10). After that in body tag, i write center tag to make button align center.(in line 11 opening tag and in line 14 closing tag ) , in center tag for clickable button i use a javascript function named as onclick()(in line 12 or 13). finally i close the body tag(in line 15) and html tag.(in line 16).

<!DOCTYPE html>
<html>
    <head>
        <title>buzzer control </title>
        <script type="text/javascript" src="https://cloud.boltiot.com/static/js/boltCommands.js"></script>
        <script>
        setKey('{{ApiKey}}','{{Name}}');
        </script>
    </head>
    <body>
        <center>
        <button onclick="digitalWrite(0, 'HIGH');">high</button>
