Today I used the magnet sensor to turn on and of the buzzer. When I turn the switch on the buzzer automatically turns on but when I place the south side of the magnet near the left side of the magnet sensor, or the north side of the magnet near the right side of the magnet sensor the buzzer turns of. But if I place the north side of the magnet near the left side of the magnet sensor, or the south side of the magnet near the right side of the magnet sensor the buzzer turns of. Here is a picture of me turning of the buzzer by placing the the south side of the magnet near the left side of the magnet sensor.

 

Today I used the LED readout to see Negative and Positive voltage using a rotation sensor. When I turn the rotation sensor counter clockwise, the LED readout flashes down negative voltage. When I turn the rotation sensor clockwise, the LED readout flashes up  positive voltage.

Here are two videos one of it going up and one of it going down:

Here is the finished project you can see me swinging the the magnet past the card.

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

 

Here is a picture of the sensor lab guidebook.

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.

Today I made the first project, a touch responding LED.
