Great video, thanks. How do I access each of the buttons in the code to implement something? Like say, if (button 1 is pressed){turn on an led} or if (button # is pressed){turn the led off} Do you have a sample program using this keypads code example? I would definitely appreciate such an example. Thanks

Hello, can you assign a sound for every number on the keypad that will be heard on a headphone? If so, is it too complicated for a beginner with arduino?

Great work!
Could it be pressed two or more key at the same time?

Excellent and informative video. I'm very, very, very new to arduino. I found a YOUTUBE video on using an Adafruit soundboard with multiple buttons as triggers to make funny car horn sounds. I have built this. BUT, I would like to use the 3x4 keypad as the TRIGGER for the sound board. I have the Adafruit Sound board and a Arduino UNO. How do I send the EVENT from the KEYPAD from the UNO to the SOUND BOARD. I don't know which PINS to connect to, nor how to change the code. Can you help? ... thanks!

Thanks for this video. Please also share the video for reducing the pins, in place of 7 pins in arduino.
