I am designing 8*8 reed switch matrix which will be connected to Arduino. I am using Arduino Duemilanove. I have completed the matrix portion but don't know how to connect and where to connect the other elements. My Matrix circuit( here is the date sheet of 74hc595)
I decided to use the following items:
64x Reed Switch
64x Diode (1N4148)
20x Resistors (10K)
I dont know where to place the Resistors and shift Registers and connection from shift registers to arduino. I need help in the circuit diagram. Please help me out with the circuit diagram.
