  When I think about a VPN service, the first thing that comes to my mind is all subscription-based plans. Also, there are numerous ads that YouTube or other OTT platforms always pours on us. However, those services are not the only way through which you can encrypt your online activity.

  Have you Left for work or are laying in bed and Wondering is that Door Closed? No Worries now, You can Remotely Control the Door with this..

  The Air Quality Terminal can be used as an indoor air quality meter to monitor VOCs, CO, NO2, C2H5CH, Temp and Humidity.

In this simple DIY Project, I will show you how to design and implement a PIR Sensor based Security Alarm System. I have designed this circuit using Arduino as the main controller and of course the PIR Sensor itself. Additionally, I have used UM3561 IC, which is a Siren Generator IC, to produce the necessary Alarm sound through a Speaker .  

  Arduino has been the go-to development platform for  fast prototyping  and idea validation. Many of us would have  started with the Arduino UNO development board , but today as we progress towards the  Internet of things , Computer Vision, Artificial Intelligence, Machine learning, and other futuristic technologies, the humble Arduino UNO could no longer cope up with its 8-bit Microcontroller. This called for the launch of new boards with more powerful processors that have built-in Wi-Fi, Bluetooth, GSM and other wireless capabilities, like the popular  MKR1000 or MKR GSM 1400 . In this context, Arduino has recently launched a new version of its Nano called the  Arduino Nano 33 . There are totally two types of Arduino Nano 33 boards, namely Arduino Nano 33 IoT and Arduino Nano 33 BLE sense. The main difference between both the modules is that the  Arduino Nano 33 BLE sense  module has some built-in sensors (will get into deta...

  Raspberry Pi  is the pocket sized computer having almost all the feature of a normal computer including USB port, LAN port, audio/video output, HDMI port etc. It also has inbuilt Bluetooth and Wi-Fi connectivity which makes it perfect candidate to build various online servers like  Webserver ,  Media server ,  Print Server ,  Plex server  etc. So here we will be creating NAS server using Raspberry Pi-   File Server or NAS (Network Attached Storage) , where you can plug any storage device with Raspberry Pi and access it using any computer connected on the same network. Using NAS, you can share and access the files and folders without actually connecting the storage device to your system. There are various methods to make Raspberry pi a NAS box. One of the method is to install disk image of  OpenMediaVault  (OMV) and  NAS4Free . They are available for free and can be easily installed by burning the fresh image into SD card, but this...
