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. <br /><br />For the sample code, show notes, contact information and many more videos, visit the show page at http://tech-zen.tv/letsmakeit <br /><br />Please subscribe to our YouTube channel or our netcasts at any of your favorite netcast / podcast outlets. <br /><br />We normally record Let's Make It live on Monday evenings around 9pm eastern. You can watch it live by going to tech-zen.tv and clicking the live link at the top of the page. <br /><br />We also have a community setup for our viewers and listeners. You can join the community by going to community.tech-zen.tv. <br /><br />We love input on what you would like to know or if you have an idea for a new Let's Make it episode, you can contact us via email or phone at the show information page. <br /><br />Producer: Mike Myers <br /><br />Executive Producer: Michelle Myers <br /><br />Shot at Crazy Eye Studios
