Hands as "flash
regulators"
YOU WILL NEED
+ your flasher circuit from
Experiment 14
+ 2 long wire connectors
+ 1 resistor, 3.3 kΩ
HERE'S HOW
1. Remove the 100-kΩ resistor from the
flasher circuit again, and replace it
with the 3.3-kΩ resistor.
2. Insert the long wires.
3. Take the two bare wire ends
