Creates an array holding button states. Includes the function checkButtonStateAndUpdate () that updates the button states. Whilst updating, the function knows that the arduino's code will run many ...

If you want to build a button array, follow this diagram. The main idea here is to connect each button to a diode in a row by column fashion, and read all the rows column by column. Rows works as ...

In the loop () we declare variable stateButton with the value obtained using the digitalRead () function that reads the state of pin 8. Then it displays its state in the Serial Monitor window as 0 or ...

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.

Earlier this year we showed you a slick MIDI sequencer project that was constructed using an Arduino Mega, which also happened to drive an incredibly detailed touch screen display.

My daughter likes buttons. She's learning letters. I was bored over winter break and had these parts laying around... so I built her a "Button Box" based around an Arduino. Open source, hackable ...

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 ...
