Step 3. Solder the LEDs Step 4. Solder the Ribbon Cable

Place the LEDs into position, ensuring they are the We are going to use three lengths of ribbon cable,
correct way around. Then, starting at one end of each with six wires. At the stripboard end, the

LEDs as straight as possible, solder one lead of the end, the ribbon cable will be soldered to header

the wires. This is a tedious job as there are 36 ends
to be stripped. When all the ends are stripped, they
need tinning with solder.

Solder each lead to a header strip (Figure 8-9)
