Arduinos Map Function and How to Use it

What is Arduinos Map Function? Arduinos Map Function is a useful utility function that helps you remap or scale a value from one range to another. It's often used to convert an input value (e.g., from a sensor or user input) that falls within one range to an output value that falls within a different range. This is particularly handy when you need to adapt sensor readings to control actuators or display data on a screen with Arduino. Here's a…

Pull-Up and Pull-Down Resistors with Arduino

What are Pull-up and Pull-down Resistors? In Arduino programming, INPUT_PULLUP and INPUT_PULLDOWN are two options you can use when configuring digital pins as input pins. These options help you enable built-in pull-up or pull-down resistors on the pins to ensure a stable logic level when the pins are not actively being driven high or low by external components. There is also another way to create pull-up and pull-down resistors.INPUT_PULLUP: When you configure a digital pin as INPUT_PULLUP, you are enabling…

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…

Programming RGB LEDs with Arduino

What is an RGB? An RGB LED is a type of light-emitting diode (LED) that can produce multiple colors by mixing different intensities of red (R), green (G), and blue (B) light. It combines three individual LEDs, one for each color component, into a single package. By controlling the brightness of each of these three colors, you can create a wide range of colors (16 million+). This guide will walk you through programming RGB LEDs with Arduino.Components:To use an RGB…
