DIY Raspberry Pi Smart Home Door Lock @Raspberry_Pi #PiDay #RaspberryPi

from Paul Freeman-Powell via hackster.io

In this DIY Gadget build, we’ll be building a secure door entry system using a Raspberry Pi.

You already may be familiar with two-factor authentication for logging into secure systems like your online banking or your Facebook or email accounts. This door entry system goes one step further and uses THREE factor authentication. To unlock the door, you require;

  • An RFID keyfob
  • A 6-digit PIN
  • A random one-time access code which is generated and sent as a text to your phone.

The very first thing we need to do is get our LCD touchscreen working. Depending on which model you purchase for your build, it may just come with drivers to install or it may come with its own Operating System image for you to write to your Raspberry Pi’s SD card. That’s the case with my one, so I need to use Win32 Disk Imager to write the image to my SD card. Make sure you select the correct device to write to, so you don’t accidentally erase any external hard drives!

Once that’s complete, pop the microSD card back into the Raspberry Pi and fit the LCD to the GPIO ports like this, starting at the top end which is by the SD card slot and away from the USB and ethernet ports. Next, take the microUSB power lead and plug it in to boot up the Rapsberry Pi to confirm that the screen – and the touchscreen element of it – are working correctly.
