In myOpenLab your device will consist of two parts: a diagram and a front panel. ... I wired two buttons connecting an Arduino’s pins 7 and 8 to ground, each with a 10K pull-up resistor.

The button states could easily be read by using an Arduino’s analog input. A Pro Mini model was chosen for its small size as it could be housed in the radio compartment of the dash.

You can read the state of a button using Arduino and a few lines of code. The actual state is shown in the Serial Monitor window as 0 or 1, 0 meaning the button is not pressed and 1 that the button is ...

While you hopefully don't need one-button access to 911, a desk-mounted panic button is undoubtedly cool, and it makes for a great DIY Arduino project. You'll need a prepaid SIM card, an Arduino ...
