| | | | | How to create music with PWM signals and Lego motors. You can generate melodies like The Imperial March tune, demonstrated in the following video. https://www.youtube.com/watch?v=mrM1pdW-Y7k The principle The sound is produced by driving Lego motors with PWM signals of different frequencies. PWM (Pulse Width Modulation) means switching the motor voltage on and off very quickly,... | |

| | | | | In this tutorial, I will explain the theory Pulse Width Modulation (PWM), and how to use it with an Arduino to control the brightness of an LED. Generally, any digital device like an Arduino deals only with two states i.e. ON(5v) or OFF(0v). However, in many situations we desire to have analog states which are... | |

This first post covers some background leading up to the project and the overall system design. I will detail the installation process, the first full year of operation, and the production and financial results in subsequent posts. | ||
