My Arduino project

After a couple of weeks working with Arduino and learning how to use different components, it’s time you think about something cool to do with it. It really is up to you, as you can choose any project you like as long as we have all the needed materials.  Be […]

Encoder and servo 6

In this activity you’ll learn how to control a servomotor with an encoder. A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to an analog or digital signal.


PIR sensor 3

In this activity you’ll learn how the PIR sensors work. A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. We’ll use it to turn a led on or off.
