ARDUINO TUTORIAL 68: Make a Remote Controlled RGB LED with Brightness and Color Control

This is our Remote Controlled RGB LED

In this lesson we take you through step-by-step instructions on creating a remotely controlled RGB LED.  This is the solution to the Homework Assignment given in Tutorial 68. It is important for you to try and complete this on your own before looking at my solutions.

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.

This video steps you through our build.

Below is the code we developed in this video.

Arduino Tutorial 36: Understanding How to Use Tilt Switches in Your Projects

This Circuit Gives Visual Indicator if Board Has Been Tilted

This is a simple project that allows you to create a circuit which will give a visual indication if the breadboard has been tilted. In the upright position, the Green LED is illuminated. To the left of the board is a tilt switch. If the project is tilted, the switch will go from the closed to the open condition. This can be detected on the arduino, and then the red LED is illuminated. The video below explains how to do this simple project.

You can get the kit we are using in these lessons HERE. You should create your own code based on the instructions in the video, but if you are having trouble, I include the code developed in the video below:


Arduino Tutorial 29: Using Push Buttons to Create Dimmable LED

In this lesson we show you how to create a Dimmable LED using two pushbuttons. Pressing one button will gradually increase the brightness, while pressing the other button will gradually decrease the brightness. The project also includes an active buzzer to provide the user feedback that either maximum or minimum brightness have been reached. I encourage you to try and build this yourself before watching the video. Then see if you can do it on your own, and then see if you are doing the way I do it, or if you find an alternative suitable solution.

If you want to follow along at home, you can order the Arduino Kit we are using HERE.

Below is the code we used to achieve the toggle operation. The video gives details on how to connect up the circuit.
