Arduino Tutorial 65: Creating Useful Commands from IR Remote Buttons

IR Remote
Simple Demonstration of IR Remote Control of Arduino

In this lesson we show you how to map button pushes on the Infrared Remote Control to useful functions in the Arduino. This code can serve as the basis for using the remote control in many different applications.

We are building this with parts from our Elegoo Kit , and our actual build is using an Arduino Nano, which allows the project to be built on a single breadboard. You can get the neat jumper wires HERE.

The code developed in the video is available below:

 

Arduino Tutorial 64: Understanding and Using the Infrared (IR) Remote to Control a Project

Simple Demonstration of IR Remote Control of Arduino

The Elegoo Kit contains a simple IR module and remote which allow you to add remote control to your arduino project. In this lesson we show you how to connect the remote, and then how to send signals to the arduino using the remote unit. This video takes you through the process step by step.

The code below will get you started, and then you can expand the code to map all the buttons to simple string commands.

Arduino Tutorial 62: Understanding How to Use Dimensional Analysis


Dimensional Analysis is one of the most important tools used by practicing engineers and scientists, and allows you to convert from any set of units to any other set of units. It provides an a methodical method that takes the guess work out of conversions. This video takes you through the method step-by-step with several examples. The homework should be done before watching the next video.

Arduino Tutorial 61: Improving Precision of Your Distance Measurements

HC-SR04 Ultrasonic Sensor in a Distance Measuring Project

In this lesson we strive to improve the precision of our distance measurements using an average of a large number of measurements. This builds on the work we did in the last few lessons.
