Study the breadboard.
What, if anything, is wrong with the circuit?
The wires are not properly aligned (move them one spot over)
There is too much power going to the LED (no resistance)
There is no power source
The wires do not complete the positive/negative circuit

There is too much power going to the LED (no resistance)
There is no power source
Nothing is wrong. The LED will light up.
You will need to add two wires to complete the circuit. Select the answers that would complete the circuit. (You may select multiple choices)
Connect row 14 to the negative rail
Connect row 14 to the positive rail

Connect row 23 to the positive rail
What if anything is wrong with the circuit in the attached image?
The positive and negative wire need to be switched.
The button cannot have positive AND negative going to it.
The LED needs to be flipped.
Nothing is wrong with the circuit
What if anything is wrong with the circuit in the attached image?
The positive and negative wire need to be switched.
The resistor has a "dead end" path
The LED needs to be flipped.
Nothing is wrong with the circuit
What is the purpose of using a resistor in a circuit with an LED and GPIO pins?
To provide a path for ground.
To increase the brightness of the LED.
To switch the LED on and off automatically.
To limit the current and protect the LED.
