4
into socket, screw the photoresistor to X3
!
While assembling the components marked
with an exclamation mark attention should
be paid to their polarity. Symbols of the
components on the PCB as well as photos of
assembled sets may come in useful. To access high-
resolution images, download the PDF file.
