LDR (Light-Dependent Resistor) Module or, photoresistor, is a type of resistor where resitant value change with intensity of light. This module has 4 pin: VCC GND DO (Digital) AO (Analog) Digital ...

The Arduino Uno Light Sensors detect ambient light levels. They typically use photodiodes or photoresistors to measure changes in light intensity. Commonly employed in automatic lighting systems, ...

In this experiment we are going to use a element called photoresistor. This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light ...

In this project we are going to interface TCS3200 color sensor with Arduino UNO. TCS3200 is a color sensor which can detect any number of colors with right programming. TCS3200 contains RGB (Red Green ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...
