5.6 LED CONTROL

In the sixth project of our electronics adventure, we use our rotary encoder to control the brightness and color of LEDs - a simple yet fascinating way

to immerse yourself in electronics. The rotary encoder, our central control element, enables playful interaction thanks to its dual function. Changes in

brightness are controlled by rotation, while pressing the encoder cycles through the LED colors - ideal for illustrating the basics of electronics and color

mixing.

ROTARY ENCODER: The rotary encoder is a clever little device that converts your rotary movements into

electronic signals. Imagine a rotary knob like the one you know from a radio. When you turn this knob, the

rotary encoder can measure how far and in which direction you have turned it. This information can then be

used, for example, to change the volume, navigate through menus or, in our projects, adjust the brightness of

LEDs.

Rotary encoders oen also have a built-in button - this means they can also function as a pressure switch. When

you press the rotary knob, the rotary encoder recognizes this pressure as a separate signal. This can be used for

various functions, such as switching a device on and o or changing operating modes.

TO SUMMARIZE: A rotary encoder allows you to send various commands to your electronics projects by turning

and pressing. It is an intuitive and versatile tool that makes interactions with your projects easy and fun.

First connect the rotary encoder to your Raspberry Pi Pico as follows:

ATTENTION! For this project, it is necessary to set the switch for

the TFT DISPLAY to OFF and the switch for the LEDS to ON.
