Arduino-Controlled Light-Sensitive LED Circuit
Image of Measuring Brightness with Arduino UNO and LDR: A project utilizing Mean Well HDR-30-5 in a practical application
This circuit is designed to measure ambient light levels using a photocell (LDR) and adjust the brightness of an LED accordingly. The photocell and a 10kΩ resistor form a voltage divider connected to the Arduino's analog input A0, while the LED is driven by digital pin D11 through a 220Ω current-limiting resistor. The Arduino's firmware reads the light level, inverses the value to increase LED brightness as it gets darker, and outputs a corresponding PWM signal to control the LED intensity.
