Record the measured time (the capacitor’s discharge time) in the 470 Ω row of
Table 5-1.
Disconnect power from your Board of Education or BASIC Stamp HomeWork
Board.
Remove the 470 Ω resistor labeled R
145, and replace it with the 1 kΩ resistor.
Reconnect power to your board.
Record your next time measurement (for the 1 kΩ resistor).
Repeat these steps for each resistor value in Table 5-1.
