The LDR is a resistor that varies in resistance when 
it catches light. The LDR is non-polarized so it can be 
soldered in either direction. 

Please make sure that you do not solder the LDR to 
tight on the PCB but make sure that a small part of 
its legs still stick out so that you can eventually 
bend it in the direction of the LED.
