I recently came across this "Instructable" in which the user ahmedelsayed93 has created a project to detect obstacles in front of an ultrasonic sensor using Arduino Uno board. What is so great about it you ask, the video shows the ultrasonic sensor mounted on top of a servo motor to make a Radar detector and the plot on his screen makes it look like the radar images we see in movies and weather channels .   The servo motor is controlled using an Arduino Uno which is communicating the sens ...
Note: This is the final part in a three-part series about the Infineon RGB LED Shield. Part 1 covered how to get started with the RGB LED Shield and Part 2 covered a white LED lighting project.   Introduction Part 2 in this series of posts covered white lighting using the Infineon RGB LED Shield. The light was controlled with a variable resistor connected to an on-board analog-to-digital converter. This Part 3 covers color lighting with this Shield.   The Infineon RGB LED shield is a ...
