VOM meter basics

VOM/DVM

Part one: record your results and email along with diagrams and photos of your work

test DC voltage with different batteries
how can larger batteries have the same voltage?
test AC voltage (V) at several outlets
test V also between each AC side and ground
which side of the outlet is “hot”? what color is this behind the wall? (look this up)
test continuity with the sound tester on metals and plastic
what makes good conductors/insulators?
test Ω across your body
why does this change?
measure mV across your body, why does this change?
test various electrical devices for resistance: lightbulbs, hot water heaters, appliances (across the cord)
determine the voltage of at least three AC and three DC sources, with explanation of each (solar panel, plugs, power supplies)
if available, test the voltage of the 12V battery in a non-EV car
start the engine, what does this tell you?
turn on the headlights, what happens?

Arduino parts part: Each kit should have these. Count them out into a new bin for your next kit:

test jumper wires for continuity, and count them out into a new bin
test the resistance of an LED forwards and backwards. Why?
confirm the resistance of both resistors
Don’t test the diode it will burn out
measure the resistance of the potentiometer (volume control) while moving the knob. It has three wires, measure across and from the middle to the ends
measure the resistance of the photoresistor in dark and light-explain
look up what a piezo element is, and what it does, then find a way to test it
skip the temp sensor and the transistor, you could burn them out with the meters
check the motor for both resistance and voltage (only when you spin it)
diagnose which terminals on the pushbutton switch do what
leave the servo, relay and integrated circuit for later
