Project #95
OBJECTIVE: To use water to control the space war integrated
circuit.
Add the press switch (S2) to the preceding circuit to make it look like
the one at left. There will be sound if the press switch is pressed or
the jumper wires are in the water.
Pressing the press switch or pulling the wires out of the water
changes the sound played.
If you prefer you can just touch the jumper wire metal with your
fingers instead of putting the jumpers in the water. Wet your fingers
to get better electrical contact.
Noisier Water Space War
OBJECTIVE: To use water to control the space war integrated
circuit.
Project #97
Use the circuit from Project #95. Replace the speaker (SP) with the LED
(D1), positioning it as in Project #89. Putting the jumper wires in the
water OR pressing the press switch (S2) will cause the LED to be bright.
Project #96
Light/Water Space War
OBJECTIVE: To control the space war integrated circuit.
Use the circuit from Project #96. Replace the LED (D1) with the 2.5V
lamp (L1). Putting the jumper wires in the water OR pressing the press
switch (S2) will cause the lamp to be dimly lit. Putting the jumper wires
in the water AND pressing the press switch at the same time will cause
the lamp to be much brighter.
