Using Basic Logic Gates – With & Without Arduino

Basic Logic Gates

Basic Logic chips have been around for a very long time, yet they are still used in new designs. An understanding of how basic logic chips work will move your design skills up a notch.

Today we will look at the most elementary of logic chips, the basic gates. We’ll also learn about logic families, and we’ll see how to create a logic chip emulator using an Arduino.

We’ll finish up by designing a simple intruder alarm using an Arduino and a basic logic gate.

Experiments with the RCWL-0516 – Doppler Radar Distance Sensor

RCWL-0516 Microwave Proximity Sensor

The RCWL-0156 is an inexpensive yet useful proximity sensor that can be used on its own or with a microcontroller like an Arduino Uno.

The device is unique in that it uses microwaves and Doppler Radar to detect moving objects

In this article I will show you how the device works on its own and how we can add an Arduino (or two) to create some useful projects
