WebMay 6, 2024 · In a button + pull-up/down configuration, your switch connects directly to the input pin, along with a resistor to either V+ (pullup) or Ground (pulldown). The other side of that switch (open until the button is pressed) connects directly to the opposite rail. When the button is not pressed, the state of the input is determined by the resistor. WebThe Arduino code we'll run later makes use of a GPS receiver, Antenna, and Temperature Sensors. An antenna tuned to 144.39MHz (or more generally the 2-meter band) The HX1 requires an external antenna to operate. We'll show you how to construct one later in this guide. An amateur radio license.
