In this tutorial we will build a simple circuit that uses a 555 timer and a Bare Paint potentiometer to make an interactive noise-maker. Before you dive into this tutorial it is worth checking out one of Matt's tutorials on building a potentiometer using Bare Paint. It is a good introduction to painted potentiometers, but not essential if you don't have an arduino. Also, if you are new to the 555 timer and are interested in playing around some more with this little chip, check out one of our earlier tutorials here.

By the end of this tutorial you should have a working 555 noise maker circuit connected to a potentiometer made from paper and Bare Paint. You will be able to change the sound of coming out of the speaker by changing the position of the slider on the painted potentiometer.

In this tutorial we will need to connect to the paint again from our breadboard. Last time we used paperclip wires, but this time we are going to try something else. We are going to use a bulldog clip to connect more securly to the paint and use the slider wire to vary the position on the painted strip.

Hey, where did you get that song in the background?
It's very similar to the old folk song from Serbia.
Here is a link so you can compare.

Hi Project23,

We got the song from the Free Music Archive http://freemusicarchive.org/. Glad you liked it!

Hey,

It is the same song! The group singing it in the video tutorial is called Gogofski. Here is a link to download their album "Music of the Balkans".

Thanks for the link - great hearing the version by Vasilija Radojcic.

Thanks!
