Raspberry Pi Tutorial 33 – Wireless Pi to Pi Python Communication with NRF24L01+ Part 2

The NRF24L01 + is an inexpensive low power high speed communication device! It’s not exactly plug and plug on a Raspberry Pi though, as compared to a wifi dongle. Building upon the previous tutorial, in this tutorial I show you how to establish two way communication between two Raspberry Pis connected to two NRF24L01+ transceivers! I’m talking master and slave communication style simulating pulling data from a sensor.  

Raspberry Pi Tutorial 32 – Wireless Pi to Pi Python Communication with NRF24L01+ Part 1

The NRF24L01 + is an inexpensive low power high speed communication device! It’s not exactly plug and plug on a Raspberry Pi though, as compared to a wifi dongle. In this tutorial I show you how to establish one way communication between two Raspberry Pis connected to two NRF24L01+ transceivers!  

Raspberry Pi Tutorial 31 – Catching the Cookie Thief

Putting together what we’ve learned from the past few Raspberry Pi tutorials, we catch our Cookie Thief!   This video is part of a series of building a practically ‘useful’ security system using Raspberry Pi to catch the Cookie Thief. I am not a computer scientist, software engineer, programmer or electrical engineer. Everything I cover was self taught using resources I found on the web. I thought it would be great to put together a series of videos that consolidates what I have learned to yield a single resource to cover many interesting topics about the Raspberry Pi! Having said…

Raspberry Pi Tutorial 30 – Transfer or Backup a File using Socket File Transfer!

This video is part of a series of building a practically ‘useful’ security system using Raspberry Pi to catch the Cookie Thief. I am not a computer scientist, software engineer, programmer or electrical engineer. Everything I cover was self taught using resources I found on the web. I thought it would be great to put together a series of videos that consolidates what I have learned to yield a single resource to cover many interesting topics about the Raspberry Pi! Having said that, due to my relatively little experience, I may have made mistakes or could have done certain things…

Raspberry Pi Tutorial 29 – Practical Socket Communication

The last couple videos setup our server and client using trivial text based examples. We need to get this doing something practical! I show you how to flip a relay based on temperature readings from a TMP36. Starting to bring it together.   This video is part of a series of building a practically ‘useful’ security system using Raspberry Pi to catch the Cookie Thief. I am not a computer scientist, software engineer, programmer or electrical engineer. Everything I cover was self taught using resources I found on the web. I thought it would be great to put together a…

Raspberry Pi Tutorial 28 – Socket Communication 2

How to setup the client side of the other Raspberry Pi, allowing us to communication through TCP and get some data sent!   This video is part of a series of building a practically ‘useful’ security system using Raspberry Pi to catch the Cookie Thief.
