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 ...

If you want to make your Arduino project more compact, an Arduino Shield is the answer. The Arduino Shield is a neat piece of hardware that sits on top of your Arduino board. It is typically designed ...

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.

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 ...

developers and hobbyists that enjoy tinkering with Arduino wearable open source electronic hardware and creating projects using Bluetooth connectivity, may be interested in a new tiny button sized ...
