Step 9: LED
Take two potentiometers or toggle switches, and two jack sockets. Install them into
places for P1, P2 (SW3, SW4), J1 and J2 but do not solder them. Then insert five LEDs
keeping the correct polarity. Anodes are indicated by the “+” sign on the board and the
longer pins. Remove the film from the front panel if there's any, and install the panel
onto the board through the switches and jack sockets. Holding the panel, turn the
module upside down and let all diodes slip into their holes. Then solder them one by
one keeping the correct clamping of the panel and LEDs' height.
Now, take off the panel and proceed to the next step.
