Introduction  
===Introduction===
Sensors are used to measure the temperature, soil moisture, water salinity, AC/DC amps, etc. Sensors also have different modes. Some of the modes include, voltage mode, resistance mode, pitch mode etc. Sensors are used to build interesting things some examples are carbon microphones, doorbells/ burglar alarms, photovoltaic panels, etc. Sensors are also used to connect to microscopes, telescopes, and many, many more things. All these sensors can be accessed through Turtle Art.

6. Inside the repeat put another x/y block. In the x input connect a xcor block which can be found under the turtle. In the y input connect a loudness block that can be found under the wire symbol.
7. Then have a blank block. This block can be found under the repeat symbol.
8. Connect yet another x/y block. In the x input connect a + block. This block will be found under the 123+-= symbol.For the top value on the + block connect a xcor block. For the bottom value connect a number block with a 1.
9. For the y value on the x/y block connect s ycor block. Your blocks should look like this:

Scientific Sensor Application


You can use a LDR or Light Dependant Resistor to measure your pulse. A LDR is a sensor because it senses light and uses it to work. You will have to put a Cartesian block after the start block. Then connect a forever block, followed by a clean block. Connect a pen up block, followed by an x/y block. For the x input you will need a –600 block, in the y input you will need a 0 block. Then connect a pen down block, followed by a repeat block. The repeat block should be connected to a 1200 block. After the repeat block should be an x/y block. For the x input you should have a + block. Connect the top of the + block to an xcor, connect the bottom to a 1 block. For the y input you should have a – block. Connect the top of the – block to a resistance block. The bottom should be connected to a 3000 block. To test your sensor, cover the LDR with your fingertip and hold near a bright light. Your test should look something like this:
