Raspberry Pi LESSON 36: Motion Detection Alarm System With LCD and KeypadVote
Announcing the Most Awesome Raspberry Pi Lessons of All Times! This time we RUMBLE!
In this video lesson I will show you how to build a portable Raspberry Pi Alarm System. We incorporate a PIR motion sensor to detect intruders. User input is via a 16 button keypad, and the system has a LCD screen. In this initial version we do not include an audible alarm but that will be added in the next lesson.
If you want to grab those cool little straight jumper wires I am using to keep my breadboard builds neat and clean you can snag a box of them here:
If you guys are interested in the oscilloscope I am using, you can pick one up here (affiliate link):
You guys get your hardware ordered so you can follow along at home!
You will also need a Raspberry Pi. I suggest the Raspberry Pi 4. If you do not already have one, this is the most suitable gear I could find:
The Raspberry Pi's are sort of pricy right now, so you can look on ebay or elsewhere to see if there are any deals. You will need a SD card. If you do not already have one, this is a good one:
I like using a wireless keyboard and mouse to have fewer wires. You can certainly use your USB keyboard and mouse, but if you want a nice wireless one, this one works on the pi. We demonstrate this by using a button switch to control a LED.
You guys can help me out over at Patreon, and that will help me keep my gear updated, and help me keep this quality content coming:
