How do I connect the LEDs?

Hold your LED against the light and inside, the cathode end inside (as shown 
in above picture) should match up with the flat side on PC board marking 
(silkscreen).  

How do I distinguish C1 and C2?

C2 is the larger capacitor, whereas C1 is the smaller capacitor.  

Assembly tips

The pins can be bent suitably to attach on the PCB.

While assembling, solder the components with many pins first, (such as 
IC) and then solder components with lesser number of pins. Finally solder 
the connecting wires.

Warnings

Wear Eye protection gear while assembling the kit.

Soldering iron is hot, and be careful while handling it.

While soldering, do not heat components any longer than 10 seconds, it 
may damage the components.

The fumes generated while soldering may be harmful. Work in a well 
ventilated area and do not breathe the fumes.

The soldering metal may contain lead. So wash your hands thoroughly 
with soap after handling such materials.

When fully assembled, test with a 9 volts non-RCX power before 
attaching to RCX.

 Improper assembly may damage kit components.
