This tutorial was featured on the official Arduino blog on 3/9/2011

That’s right folks, it’s Monday, and the second installment of my arduino tutorial series is here! I spent the last week in Disney World, but now that I’m back, it’s time to get down to business! This week, I’ll show you how to read a push button, debounce its input using software, how to create a function in the arduino programming environment, and how to change LED brightness using Pulse Width Modulation (PWM). If you have no idea what PWM is, or if you are confused about analog and digital signals, go check out my TechBits episode on the topic first! Don’t forget to go browse the element14 Arduino Group; it’s a great place to post questions, and learn from others!
