1. Push Button LED Control
This example demonstrates how to control an LED using a push button. When the button is pressed, the LED turns on; otherwise, it remains off. The button state is also printed to the serial monitor.
int led = 13;
int pushButton = 2;
void setup() {
Serial.begin(9600);
pinMode(pushButton, INPUT);
pinMode(led, OUTPUT);
}
void loop() {
int buttonState = digitalRead(pushButton);
Serial.println(buttonState);
if (buttonState == HIGH) {
digitalWrite(led, HIGH);Economic Liberalism: Principles, Evolution, and Modern Relevance
Understanding Economic Liberalism
Economic liberalism is a theory that promotes individual liberty, free markets, and limited government intervention. It is based on the view that humans are rational beings driven by self-interest, which, when regulated by market competition, can lead to socially beneficial outcomes. Emerging in the 17th and 18th centuries as a response to mercantilist policies, economic liberalism advocated for less state interference in economic affairs. Early contributors such

Historical Background: 19th and 20th Centuries
The historical background spanning the 19th and 20th centuries is characterized by a disparity of approaches, largely driven by significant social, cultural, and political events. Industrialization was a foundational characteristic of this era. While it was hoped that industrialization would alleviate human misery and foster a social order promoting cultural and moral development, it instead

Visual Recording: Reactivity and Privacy Concerns
Visual recording methods often trigger reactivity in research subjects. Cameras, in particular, can be highly intrusive, leading to an explicit loss of anonymity. While their use in open environments might sometimes be overlooked, it frequently faces strong rejection. When observing actions in private spaces, the use of visual recording requires an intense and arduous negotiation process.
