OBJECTIVE: Construct a light-controlled display.
Connect segments B & C to the circuit. Turn on the switch (S1),
the display should be off. Place your hand over the photoresistor
(RP), now the number 1 lights.
Automatic Display #1
Project #467
OBJECTIVE: Light the number 2 using a light-controlled
display.
Use the circuit from project #467. Connect A, B, G, E, & D to the
circuit. Turn on the switch (S1), the display should be off. Place

Automatic Display #2
Project #468
Project #466
OBJECTIVE: To build change the direction in which current
flows.
Compare this circuit to project #358, which has the LED (D1 & D2)
positions reversed. This changes the direction that current can flow.
Set the meter (M2) to the LOW (or 10mA) scale. Press the press
switch (S2) and now the meter deflects to the left.
