- What are input sensors?
Input sensors are devices that detect changes in the environment and send signals to the Arduino. They help Arduino understand its surroundings. - How does a push button work as input?
When you press the button, it completes a circuit and sends a signal (usually HIGH) to the Arduino. It’s like saying “Yes” or “Now!” - What is an LDR and what does it do?
An LDR (Light Dependent Resistor) changes its resistance based on light. More light = lower resistance. Arduino can read this change to know if it’s bright or dark. - Where are these inputs connected?
- Digital pins for on/off signals like buttons
- Analog pins for variable signals like from LDR or temperature sensors
