The SG90 is a <strong>standard servo<\/strong>, meaning it has a limited range of motion typically between 0 and 180 degrees. It&#8217;s commonly referred to as a &#8220;directional servo&#8221; because it can rotate to a specific angle in either clockwise or counterclockwise direction, making it suitable for applications where precise positioning is required.<\/p>\n<ul>\n<li>The SG90 servo has a limited range of motion, usually between 0 and 180 degrees. This makes it suitable for applications such as controlling the movement of robot arms, steering mechanisms in RC vehicles, or controlling flaps on model airplanes.<\/li>\n<li>Like most servos, the SG90 is controlled using PWM (Pulse Width Modulation) signals. By sending PWM signals with different pulse widths, you can command the servo to move to a specific angle within its range.<\/li>\n<\/ul>\n\n<\/div><h2 class=\"tabtitle\">Wiring Diagram<\/h2>\n<div class=\"tabcontent\">\n\n<h3>Wiring Diagram<a href=\"https:\/\/learnlearn.uk\/stemrobotics\/wp-content\/uploads\/sites\/28\/2024\/02\/Servo-Microbit-Breadboard.png\"><img decoding=\"async\" loading=\"lazy\" class=\"size-medium wp-image-96 alignright\" src=\"https:\/\/learnlearn.uk\/stemrobotics\/wp-content\/uploads\/sites\/28\/2024\/02\/Servo-Microbit-Breadboard-300x245.png\" alt=\"\" width=\"300\" height=\"245\" srcset=\"https:\/\/learnlearn.uk\/stemrobotics\/wp-content\/uploads\/sites\/28\/2024\/02\/Servo-Microbit-Breadboard-300x245.png 300w, https:\/\/learnlearn.uk\/stemrobotics\/wp-content\/uploads\/sites\/28\/2024\/02\/Servo-Microbit-Breadboard-768x628.png 768w, https:\/\/learnlearn.uk\/stemrobotics\/wp-content\/uploads\/sites\/28\/2024\/02\/Servo-Microbit-Breadboard.png 1022w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/h3>\n<p>Wiring up the servo to the Microbit is easy.
