Assignment
Assignment
Design, simulate, and build a simple electronic device that performs two actions at the same time. The device may serve a need at your home, or just fun to build!
Requirements
The device must perform 2 actions at least: emits light - makes noise or sound - makes movement (Emits light & Makes sound)
The device must have a power ON/Off switch (it has a power ON/OFF)
The device must perform an action only when a switch is closed or opened, or when a resistor value has changed (LDR, Thermistor, Potentiometer...etc..).
(It does)
Calculate the required current for each of the action components in your circuit using Ohms' Law, and verify the calculated value using the Avo-meter. Calculate the value of the current limiting resistors (If any).
The Required Current= V/R = 9/(340+1K) = 6.716x10^-3 A

Problem: First I was connecting the pushbutton directly to the buzzer not the potentiometers; only one worked and the others didn't that's why I changed the connections...and it worked!!
Solution: Changed the connections
WOW!
