Infrared Receiver (IR) Demo with Arduino

I remember back in the day when my father had two remote controls for the television, me and my younger brother. “Howard! Change the TV to channel 5.” I also operated as the television tuner by going outside and turning the antenna until I heard him shout to stop. My kids can not even comprehend

Lego Record Player Using an Arduino and a Servo Motor

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 my handy, dandy servos and

An Arduino With Two Servo Motors

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() function in the Servo library

Using an Arduino to Contol a Servo Motor

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 0 position and rotates it
