In this instructable I made a circuit that generates tone with Arduino. I really like simple and fast to build projects. Here is a simple project of this kind.
This is a show and tell project that I made exactly using documentation from Arduino website.
In this post, I’ve tried to generate tones with Arduino board.
Using Arduino Uno and an 8 ohm speaker, you can easily generate tones and sounds.
This Arduino sketch uses Tone function to generate sounds.
Step 1: Components and Circuit
Arduino Uno or any other Arduino board will do.
8 Ohm Speaker
The circuit is very simple.
Connect the speaker to Arduino board on PIN 8 and GND.
Step 2: Simulation and Code
Simulation is a great tool to test your design before actually building anything. You can also use simulation when you don't have the hardware and you need to get started.
In this simple circuit, simulation is only used for clarifying the concept and showing how it works.
There are many Arduino simulation software. In this instructable, I used Autodesk online platform Tinkercad.
You can see the circuit and start simulation. You can edit it and change the code to your needs.
You can build any circuit you like and you can also browse all projects to find what you are looking for.
Here is the post on my website
Step 3: Build Real Circuit
Now you can build the real circuit and upload Arduino sketch to the board.
Here is the video of the circuit in action.
