Now, it’s time for more capacitors. Take the two 47μF capacitors and place them on the front
side of the board. Be careful, these are
polarized!
capacitors and should be soldered the
right way
in. There is a + marking on the circuit board that should match the long lead of the
capacitor, the – side is also marked on the body of the capacitor with a white strip.
Also solder the 16MHz resonator, its an orange component with 3 leads, don’t worry it’s not
polarized. Your board should look like this now.
