Here is a picture of a bunch of jumbled up cords.

Today I used a magnet to alter a buzzer. like my last project when I swing a magnet back and forth past the magnet switch card the buzzer changes noises from very high pitch to a little bit lower pitch.

Here is a picture of me testing the project out you can see me swinging the magnet like a pendulum back and forth.

Here is a picture of me making the magnet responding LED.

Here is a picture of the sensor lab guide book on the page with instructions for making a magnet switch on with an LED.

Today I made an Led respond to a magnet. I put the Magnet Switch Card into the sensor socket which is located above the the Breadboard. By swinging a magnet hung on a string back and fourth past the Magnet Switch Card like a pendulum the LED turns on and of.

Today I used a 100K Potentiometer to see the LED readout. When I turn the potentiometer the led readout goes up and down, here's a picture of it.
