I recently ran across an Instructable where the author showed how he had created a record player from paper. I thought that was pretty cool and decided to make something similar for myself. But rather than using paper and turning the record by hand I wanted to use one of…

In my last post I looked at using a servo motor with an Arduino and a couple of LED lights to indicate when it would rotate clockwise vs. counter-clockwise. In that post we were using a simple servo motor that had 180 degrees of rotation. We were using the write()…

I was playing around today with my Arduino, running the tutorial for controlling a servo motor. I decided to make it a little more interesting by adding a couple of LEDs. The tutorial uses PWM (pulse width modulation) to control the rotation of the servo motor. It starts at the…

I tried my hand at soldering a headphones jack recently and had difficulty with the soldering part of the process. Actually, it was only soldering so I had trouble with the ENTIRE process. It was only after I had made a rather horrendous connection that I realized I had not…
