The ultrasonic sensor I am using in the video is a transceiver, because it can send and receive ultrasonic waves.\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<h3><span style=\"font-weight: 400\">What is a Servo?<\/span><\/h3>\n<p><span style=\"font-weight: 400\">\u00a0 \u00a0 \u00a0A servo is a small motor that can be programmed to rotate a certain number of degrees at a set speed. A &#8220;continuous&#8221; servo can spin 360 degrees, while a normal servo can spin almost 180 degrees. On a normal servo, the angle of rotation and the turn speed can be adjusted. On a continuous servo, only the direction of rotation and speed can be adjusted. Servos use magnets (brushed) or a magnetic field and electricity (brushless) to determine their angle of rotation. The servo I am using in the video is a normal servo.<\/span><\/p>\n<p>&nbsp;<br \/>\n<iframe loading=\"lazy\" src=\"https:\/\/wcu.hosted.panopto.com\/Panopto\/Pages\/Embed.aspx?id=bfdd67b0-502a-469f-912f-af4c01759a8e&#038;autoplay=false&#038;offerviewer=true&#038;showtitle=true&#038;showbrand=true&#038;captions=false&#038;interactivity=all\" height=\"405\" width=\"720\" style=\"border: 1px solid #464646;\" allowfullscreen allow=\"autoplay\"><\/iframe><\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is an Ultrasonic Sensor? \u00a0 \u00a0 \u00a0Ultrasonic sensors use sound waves to measure the distance to an object.
