Project 73 2-Front Circuit
Assembly:
1. Place base grid supports on base
grid A.
2. Place parts on grids B&C, and install
into base grid supports on grid A.
Pegs on grids B&C should be facing
outward.
3. Install remaining parts on grid A.
4. Add the two blue jumper wires.
Since they are short, be sure to put
them through the holes in grid C, as
shown in the picture on the right.
Turn on the slide switch (S1) to see
light displays on the light tunnel (U30)
and the color LED (D8).
Use the preceding circuit but replace either
the color LED (D8) or light tunnel (U30)
with the white LED (D6). You may add the
projector to the white LED if desired.
