Hi, first of all I am so sorry if this thread is missplaced.
Is it poissible to build a homemade keypad? I want to build a keypad like this one http://www.sparkfun.com/products/8653 but the size isn't right for my model and I want to use another buttons etc.
No nothing advanced at all, I need to build a very simple keypad, 123..890 # and *
Press the button, release it, the pressed button (lets say 4) saves in a int variable.
Could you or someone else please redirect me to a schematic/site/anything that could help me with this?
What do I have to buy? Buttons and hookwires? Sorry but I am very new to this.
