Using Pushbuttons with Arduino. Pullup vs Pulldown resistors

Arduino IDE 2.0 (beta)

LED (generic)

Resistor 10k ohm

Arduino Nano R3

Tactile Switch, SPST-NO

<p>This tutorial covers using both external pull down and pull up resistors with pushbuttons.</p><p>Then it also shows how to use arduino internal pullup resistors associated with every Arduino digital input pin.</p><p>Here is the link to the tutorial:</p><div class="se-component se-video-container __se__float-none" contenteditable="false" style="width: 100%;"><figure style="width: 100%; height: 56.25%; padding-bottom: 56.25%; margin: 0px;"><iframe allowfullscreen="" data-align="none" data-file-size="0" data-index="0" data-origin="100%,56.25%" data-percentage="100%,56.25%" data-proportion="true" data-size="100%,56.25%" frameborder="0" src="https://www.youtube.com/embed/87X5Duad8CU" style="width: 100%; height: 100%;"></iframe></figure></div><p></p>
