8.Custom function using in Arduino Uno

Custom functions in Arduino Uno programming enhance code modularity and readability. By defining custom functions, you can group related commands into reusable blocks, simplifying complex tasks. For example, if you frequently need to control an LED in various ways, you can create a function like void blinkLED(int pin, int delayTime) to handle the LED blinking logic. Custom functions are defined with a name, return type (usually void if no value is returned), and parameters if needed. They are called within the setup() or loop() functions, allowing for clean and efficient code. This approach reduces redundancy and facilitates easier code management and debugging.
