Teardrops in PCB design are small tadpole-shaped features that enhance the connection between pads and traces or vias and traces, improving the reliability of printed circuit boards. They are beneficial in high-reliability applications where mechanical stresses and thermal expansion could lead to connection cracks. Teardrops help to strengthen these connections and prevent potential issues, making them a valuable addition to PCB design for ensuring long-term performance and durability.

![[160] Arduino Getting Started: Digital input and button](https://i.ytimg.com/vi/RK8kM8LW2Oo/mqdefault.jpg "[160] Arduino Getting Started: Digital input and button
This tutorial introduces how to integrate a push button into your Arduino projects to control an LED. Using a digital input pin, youll learn to read the state of the button and use its status to turn an LED on and off. This project builds on our previous tutorial by adding a push button and demonstrating how to set up and code for interactive elements. Through the demonstration, youll understand how to handle button states and debouncing, enhancing the interactive capabilities of your Arduino projects.
