Unfortunately, the AD9833 doesn’t have a way to control amplitude, something which is pretty important in a function generator. So [Faransky] uses a X9C104P 100KOhm 8-bit digital potentiometer ...

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 ...

When the state() function is called and an event has occured since the previous call, it returns one of the following values: PRESS_SHORT - The button has just been pushed down.; PRESS_LONG_FIRST - ...

ButtonFunction is a library for detecting button taps and long presses on Arduino. It provides a simple and easy-to-use API for registering button press events and executing callback functions in ...

The Arduino looks for two specific functions, setup() and loop(). setup() , unsurprisingly, is run once and sets up the things you need for when the program is running.

When you scroll down, you will see that there are two functions created for both the Buttons in the GUI. Now write the code in both the functions according to the task you want to perform on click. In ...

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 ...

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 ...
