Servo Pen

Last week I spent most of my time figuring out the pulse sensor, and did not really get a chance to familiarize myself with the servo. For this week’s lab, I decided to do some simple experiments with the micro servo. I attached the servo to pin 9, and tried out a few different sensors as the analog read. Below is an example using a force sensing resistor (FSR) and a micro servo attached to a pen to create abstract drawings.

It is strangely satisfying using this simple device. When drawing, I find myself carefully controlling my force squeezing the FSR to change how the pen draw.
