Remote SOund Navigation And Ranging(SONAR) Application with Raspberry Pi 2 in the Local Network Area(LAN)

Hello everybody, today I am here with another post. I will construct a remote SONAR application using Raspberry Pi 2, servo motor and HC-SR04 ultrasonic range sensor. In order to understand this post better, please check the previous posts that I have already written.

1 - Controlling Servo Motor using Raspberry Pi, Python (RPi.GPIO) software based Pulse Width Modulation(PWM)
2 - Using HC-SR04 Ultrasonic Range Sensor with Raspberry Pi 2

What do we need?

1 - Raspberry Pi 2

2 - HC-SR04 Ultrasonic Range Sensor
3 - Micro Servo Motor
4 - 1x1kΩ and 1x2.2kΩ Resistors
5 - Bread Board
6 - Jumper Male to Female Wires
7 - Laptop(for remote communication)

We need all the components above. But, if you want to display the results on Raspberry Pi locally, then you don't need a Laptop. However, here I will use Laptop. Because, Raspberry Pi is a small board which is used for remote applications generally.

Here is the technical description.

1 - My laptop's config(It will be the client machine):

- IP Adress:192.168.1.106
- Communication port is 9000
- Operating System: Windows 10
- This will be the client machine

2 - My Raspberry Pi's config(It will be the server machine):

- IP Adress:192.168.1.108
- Communication port is 9000
- Operating System: Raspbian Jessie Lite
- This will be the server machine

Live Video Streaming from Raspberry Pi using MJPG-Streamer and HTML5 in the Local Network Area(LAN)

Hello there! After Remote Connection to MySQL Database in the Local Network Area(LAN) post, I am here with another fancy topic which makes live stream over HTTP. There are many ways to do this. But after a quick search, I have found the one that leads to minimal latency and works really well over a WIFI connection. The solution is the combination of MJPG-Streamer on the Raspberry Pi and HTML5 client website on the other computer.

Here is the technical description.

1 - My laptop's config:

- IP Adress:192.168.1.106
- Operating System: Windows 10
- HTML5 client website will be implemented in this computer.

2 - My Raspberry Pi's config:

- IP Adress:192.168.1.108
- Operating System: Raspbian Jessie Lite
- MJPG-Streamer program will be installed here and it will stream live video.

Both are on a wireless LAN connected through a TP-LINK router(192.168.1.1).

One by one we need to do following steps:

Remote Connection to MySQL Database in the Local Network Area(LAN)

Hello there! It has been long time to not write any post in the blog. I do not want to say that I did not have any time, inspiration or something. I had time, really good ideas but somehow I was too lazy to write them down to the blog. But, today I wanted to break this laziness. Anyway, from the title most probably you got what I want to do. But, basically I will explain it again.

I have a private wireless LAN at home as everybody and two device is connected to this network.

Here is the technical description.

1 - My laptop's config(It will be the server machine):

- IP Adress:192.168.1.106
- MySQL Server 5.7 on port 3306
- Operating System: Windows 10
- The database is in this machine

2 - My Raspberry Pi's config(It will be the client machine):

- IP Adress:192.168.1.108
- MySQL Server 5.7 on port 3306
- Operating System: Raspbian Jessie Lite
- This machine will connect to my laptop

Both are on a wireless LAN connected through a TP-LINK router(192.168.1.1).

So the big question is that how can I configure the devices to connect to the database and execute queries?
