5.7 AUTOMATIC BRIGHTNESS CONTROL
In the seventh project of our electronics adventure, we use a photodiode to automatically control the brightness of LEDs. The photodiode converts light into
an electrical signal so that the LEDs light up brighter when it is dark and dim when there is more ambient light.
By connecting the photodiode to the Explorer Board and programming it on the Raspberry Pi Pico, the LEDs adapt intelligently to the ambient brightness.
This project shows how reactive and energy-saving electronic systems can be built with simple components.

PHOTODIODE: A photodiode is a special type of semiconductor that responds to light hitting it by generating
an electric current. Think of a photodiode like a small solar panel: when light falls on it, it converts this light into
an electrical signal. The more light that reaches the photodiode, the stronger the signal becomes.
Photodiodes are very sensitive and can detect even small amounts of light, which makes them ideal for projects
where it is important to measure the brightness or presence of light. For example, they can be used in automatic
brightness controllers, light sensors or as part of a lighting control system.
In short, photodiodes are eective light detectors that allow us to make electronic devices react intelligently to
changes in ambient lighting.
First connect the photodiode via the breadboard as follows. Please note that the use of a resistor is also required
here. Use the 100 kΩ (brown-black-yellow) resistor here.
ATTENTION! For this project it is necessary to set the switch for the RELAY to OFF
and the switch for the LEDS to ON.
