In this guide you will learn to created an array of LEDs that visually represent the volume picked up by an electret microphone. You will learn how to wire 3 different circuits which are the LED array (which is really many individual circuits), the microphone, and a button which can be used to change the display mode […]

In this project, we will combine an Arduino, a Ping sensor, and a small assortment of components, to build a project that senses distances as “hot/cold.” Once built, we’ll walk through the software running our basic “sketch,” (what an Arduino program is called) and then experiment with variations of the “hot/cold” theme, all the while […]
