Manual

Use the preceding circuit, but mount it up high so it so the phototransistor
(Q4) can better measure the room light to see if the white LED (D6) needs
to come on.
Assembly (adult supervision recommended):
1. Place base grid supports on base grid A.
2. Install grids B & C into base grid supports on grid A. The pegs on grids
B & C should be facing outward.
3. Place parts on grids D as shown in project 42.
4. Mount grid D on top of grids B & C using 4 stabilizers.
The circuit works the same as in project 42.
