3) Place diodes according marking on PCB:...
Page 4
4) Place all electrolytic capacitors. Be careful with polarity!

6) Place ceramic capacitors. Polarity is not matter: 7) Install 3 buttons:...
Page 7
8) Place photoresistor. The high should be equal of buttons.

20) Now check the resistance between GND and +3.3V pins of XS2 again. It is should be ~3kOhm. However, not lower 1 kOhm. 21) Then plug DC adapter. The microcontroller starts work and you will hear short melody. If it not happens, check the 3.3V on XS2 between GND and +3.3 pins.
