The Relay Sub BoardAttach this board to the
Simplified
I/O Interface Board
Use nine pieces of hookup wire (or a piece of ribbon cable) to
connect corresponding points on the I/O Demonstration Board to the Relay Sub
Board. Connect 12 volts DC (smoothed) to the power input points on the I/O
Demonstration Board. Solder in as many relays as you intend to use, each with
its associated LED, resistor and 1N914 signal diode.
LATEST UPDATE: The board is now designed so that it may be cut
in two to make two separate boards, each with four relays. This should be more
than adequate for most purposes.

8 x 3mm red LEDs
