Applications and Uses of LED control
Controlling the brightness of an LED with a potentiometer and an Arduino has various practical applications, particularly where changing light intensity is critical. Here are some of examples:
- Regulating Ambient Lighting: A potentiometer can be used to regulate LED strips or modules used for ambient lighting in rooms or displays.
- Display Screens Brightness: When creating projects that include screens (such as LED matrices, LCDs, or OLEDs), you may employ the potentiometer to regulate the backlight brightness of the display. This might help you adjust readability in different lighting situations.
- Photography lighting setups frequently involve the use of LEDs to generate numerous lighting effects. You may fine-tune the lighting parameters for better photographic results by regulating LED brightness using a potentiometer.
LED Control with Potentiometer using Arduino
In the field of electronics and programming, controlling an LED with a potentiometer is important too. By varying the resistance of the potentiometer, you can change the brightness of the LED. We will interface an LED (light-emitting diode) to the Arduino UNO board. An LED is a simple diode that emits light with a forward bias. We control the brightness of an LED by interfacing a potentiometer with it. We write a program in the Arduino IDE and download it to the microcontroller board.
