This week we make a simple VU meter using an Arduino.  We take audio input from either a microphone or a line level input and use a small transistor to amplify the signal, add some leds and some basic code to create a VU meter that has a switchable peak meter.

Let's Make It is a show that is all about making things, in particular electronic things.  During this show we will be using things like Arduinos, PIC chips and Raspberry Pie's to make all kinds of electronic gadgets.

We are making these gadgets to learn how they work.  Not technical, not to worry, we are going to start really simple and teach you as we go along.  All it requires is a desire to want to learn some programming and electronics.

This show is hosted by Mike Myers of Genius Idea Studio.  Mike has many years of designing hardware and developing software for the hardware.
