Draw Sound With Arduino

Drawing is fun, so is making music… So let’s combine them so we can draw sounds! It’s simple once you understand how it works. First we use a graphite pencil, the graphite is conductive but still is slightly restive. The Arduino board measures the resistance between the pencil and paper clip then converts it into a pitch that it then sends to the speaker. I added an potentiometer to further control the pitch, also it will not play unless there is contact from the pencil. You can make tons of different designs, just remember the thinner the line the more resistance there will be. I think it’s time to begin!!”
