I started exploring GitHub because I need a place to store my code online, and this seemed appropriate. 694 more words

PWM and Speed, Objects and Structs

I’m still determining how everything’s going to work…

Before we go any further, PWM refers to a number from {0-255} which corresponds to a voltage that the Arduino sends to the motor. 725 more words

Fun With Direct Digital Synthesis

You know that good feeling you get when a project comes together? Thats what I felt when I saw this sine wave on my oscilloscope.  It’s a Pulse Width Modulation (PWM) signal generated by an Arduino using a Direct Digital Synthesis (DDS) technique and a lookup table of amplitude values. 2,236 more words
