Step 3Solder wires to the lens head
Identify the contacts on the cd lens - there are four, a pair for each of the two axes.
they are connected to the flexible wires holding the moving plastic part with the lens and the coils.
Strip the ends of four wires and solder them to the contacts... be patient, these are small points to solder to.
Strip a short length at the other end of the wires and coat them with solder to make them stiff and fit better with the Arduino.
