Cindy - PM - 2 Hours - Sensors & Printers

Today in open lab, I worked on researching and running the infrared motion sensor, the photo resistor sensor, and the ultrasonic sensor. I learned that infrared sensors are used to detect infrared radiation, or heat. Photo resistors measure the amount of light it receives and ultrasonic sensors use ultrasonic waves in order to measure distance. After researching and running the sensors, I helped take apart a printer. We tried to salvage a motor from a printer to use for the claw machine, but the screw that was keeping the motor down was stuck and unable to be unscrewed. However, Mr.Burnham informed us that the motor would not be the best choice for the claw machine since the whole component rotates.
