The other wires will all be just poked into the
sockets that line the edge of the board. If you used
multi-core wire, this will be easier if you tin the
wires with solder first.
Starting with the leads from the LED, attach
them as shown in Figure 13-10. That is, one lead
to the GND socket and the other to the Digital 13
socket.
Wiring the phototransistor is a little more
difficult because we are going to attach R2 at the
same time. Put one end of R2 into the 5V socket
and fit both the other end of R2 and the lead going
to the collector of the phototransistor into the
