Re: how do I interface with a 4x4 keypad/

One Analog Input to Arduino from a keypad.
I use it, and it works fine (but it's only 3x4 matrix keypad).
Interfacing w/ Software on the Computer

I did it this way:
Read Arduino in VB:
Public iSerialReceived(50) As Integer
Function SerialReceive() As Integer
Dim iIndex As Integer
On Error GoTo ErrHandler
If SerialPort1.BytesToRead > 0 Then
iIndex = 0 'Initialize
While SerialPort1.BytesToRead > 0
iSerialReceived(iIndex)= SerialPort1.ReadByte() ' Read next byte
iIndex = iIndex + 1
...PROCESS DATA HERE OR SOMEWHERE ELSE...
You already send "LED ON"/"LED OFF" via Serial as far as i can see.

Have tested it now. Works nice!
Software serial vs serial

I wonder, is it possible use TX/RX on a arduino pro micro, communicate with a arduino uno using Serial in pro micro and software serial in the uno? The main question, is serial compatible with software serial?
