Today I used the probe to switch on either the red, or green, LED. When I place a moistened finger in the probes protruding prongs, the red LED glows. When I don't put my finger on the prongs the green LED glows. Here are to pictures, one of the red LED glowing, and one of the green LED glowing.

Today I used he probe sensor card to see the led readout. First I moisten my middle and index fingers by licking them. Next I put on rubber Crocs to ground the current. Then I turn the switch to on and the led readout switch to DOT. Then I place my two moistened fingers on the to leads coming off of the probe. When I move my fingers back and forth on the probes leads the LED readout goes up and down here is a picture of it.

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.
