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 ...

Most embedded systems are reactive by nature. They measure certain properties of their environment with sensors and react on changes. For example, they display something, move a motor, or send a ...

How do you turn an LED on and off with a button on Arduino? We set the pinButton variable as integer 8 and we connect the button at pin 8 on the Board. Then the LED is connected to pin 2 using the ...

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 ...

I wired two buttons connecting an Arduino’s pins 7 and 8 to ground, each with a 10K pull-up resistor. This biases the pin values so that MyOpenLab can read a 1 on those input pins when the ...
