Figure 13-12 is the circuit diagram, and Figure 13-13 is the breadboard layout diagram.
Depending on which key-fob receiver you have, you may need to alter the receiver pin con-
nections. In this example pin 1 is ground, pin 2 is 5V and pin 3 is data. he other pins are
usually allocated to additional key-fob buttons or a receiver aerial. Before you buy a kit refer
to the data sheet of the receiver to check the pin coniguration and check the output voltage.
