Programming the Light Dependent Resistor

What is a Light Dependent Resistor A Light Dependent Resistor (LDR), also known as a photoresistor, is a type of passive electronic component that changes its resistance in response to changes in light levels. The resistance of an LDR decreases as the intensity of light falling on it increases. Conversely, its resistance increases as the light level decreases. LDRs are commonly used in various applications to sense and control light levels. Components To use an LDR with an Arduino, you'll…

Arduino Analog Input and Output Pins

Understanding The Arduinos Analog Pins Arduino's analog input and output pins are a crucial part of the platform, allowing you to read analog voltage levels from various sensors and devices. The Analog pins are A0 to A5. First thing you need to understand is the analogRead() and analogWrite() functions do NOT read and write the same thing. The analog read function reads a voltage value which is then converted to an analog value. The analog write function writes a PWM…
