Este projeto demonstra como usar um resistor dependente de luz (LDR) como um sensor para medir a luz ambiente e controlar um LED de acordo. O código Arduino lê o valor analógico do LDR e o mapeia para ...

What if we can generate different colors using a single RGB led and make our room’s corner more attractive? So, here is a simple Arduino based color mixing lamp which can change color when there is ...

Circuit Diagram . Code and Explanation. The complete Arduino code for Automatic LED dimmer is given at the end.. In the below code, we are defining the PWM pin and the variables to be used in the code ...

A simple LDR controlled LED that cycles the LED power using a simple time based step function. It also uses simple charlieplexing to alternately light two leds using 2 wires, and that's because I use ...

Light and dark detection using an LDR. For this project, let’s stick to the LDR sensor module so we can select the light or dark detection by placing jumpers. We’ll be using this module to detect ...
