Hi guys, I need to simulate button presses to a keypad. When one of the buttons are pressed they just go to ground. I have 6 buttons and I want the Arduino to do the same thing as pushing one of the buttons. I have 6 wires from the keypad and I just want the Arduino to ground them out in an order I choose. Relays are bulky and take too much power. Is there a simpler option where I could write the pin high and it ground out my button wire?
