Yet another installment to our log of things programmed. Below is a program for controlling a motor with lights and phototransistors. I enjoy the struggles posed with programming complex systems. Even though the stress is high, the result is definetly worth it. I believe the video helps back up my last statement.The program shown below is the one in the video. Enjoy, I did!
Conclusion
1. Describe an open loop system that has not already been given as an example. Could the system benefit from feedback? Justify your answer.
Microwave is an open loop system because it has no function that allows it to know when the item inside it hot. The microwave runs for the amount of time that was put in, such as 2 minutes. If the microwave could have feedback, the microwave would be able to stop running if there was a danger or stop once what is in the microwave is a certain temperature. It would make the microwave more efficient.
2. Describe a closed loop system that have not already been given as an example. Describe the feedback utilized, and describe why that type of feedback is utilized.
Motion sensors in lights for classrooms and hallways are a closed loop system. The lights turn on when it senses movement and turns off when it senses no movement for a certain amount of time. This system of sensors allow for saving of energy and removes the need for a switch and a tangle of wires.
