This project illustrates how to control an LED with a push button connected to an Arduino board. Pressing the button will toggle the LED on and off, making it an excellent introductory project for ...

This is the first task for the Electronics and Power Department. It consists of two assignments: the first involves building a circuit with an Arduino UNO and a push button, while the second involves ...

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 resistor in series with it. In the setup() function we set the ...

In our hardware the push button is input which is connected to the second pin of the Arduino. If you take a close look you can notice that one side of the button is connected to the Ground and the ...

Interrupts in Arduino works same as in other microcontrollers. The Arduino UNO board has two separate pins for attaching interrupts on GPIO pin 2 and 3. We have covered it in detail in Arduino ...

The buttons are wired into a digital input pin and an analog ground pin. I’ve used pins 2 and 3, as you will be able to see in the code later on. Wiring up the LED matrix to the Arduino was a ...

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 ...
