📄️ The Joystick
A joystick module allows us to create interactive projects. Joysticks can provide input in the horizontal (x) and vertical (y) direction as well - just like a joystick on a games console.
📄️ Stepper Motors
Stepper motors can be used to produce motion in small steps. This allows us to program stepper motors to make very precise movements and this is why stepper motors are often used in 3D printers and robotic arms.
📄️ DC Motors
The third type of motor we will learn about is the DC motor (direct current) motor. Unlike stepper motors, which move in precise steps, or servo motors, which move to specific angles, a DC motor can spin continously when powered.
📄️ Ultrasonic Sensors
An ultrasonic sensor is a distance sensor which can be used to create projects that measure distance, for example, in obstacle avoiding robots.
📄️ Project: Obstacle Avoiding Robot
Projects are intended to consolidate the knowledge you have absorbed in previous lessons. This one will help you apply what you've learned about motors and the ultrasonic sensor.
