You will need the Arduino Board, a 560Ω resistor, and LED and the code example below. We set the pinButton variable as integer 8 and we connect the button at pin 8 on the Board. Then the LED is ...

But if you just want to add in some buttons without reaching for an extra IC you’ll love this hack. [John Boxall] shows how to add four buttons using one ADC pin. The concept is nothing new.

You can read the state of a button using Arduino and a few lines of code ... with the value obtained using the digitalRead() function that reads the state of pin 8. Then it displays its state in the ...

the Arduino would have to keep the pins as inputs until a steering wheel button was pushed, the pin changed to an output, the signal sent and the pin changed back to an input. This feature was ...

The official Arduino development team has this week announced that the latest Arduino IDE 2.0 has now been made available as a stable release and is now available to download. The second ...
