For this week’s recitation Dom and I constructed a setup where an LED light would turn on in reaction to moving our hands our an object to a close proximity to an infrared sensor. We used a resistor, an LED and the sensor to complete this task. Upon completion we altered the code to allow the LED to fade brighter as the hand got closer and dimmer when it was farther away. With some help from Katie and a fellow teacher we were able to make it work.
Documentation Questions:
- We intended to assemble a simple setup with a proximity sensor turning on a light. One practical use of such a circuit in my opinion is home defense or an alarm system. If an uninvited intruder comes to close it will trigger a warning.
- Code is compared to following a recipe or a formula because, in my opinion, just like a recipe coding requires you to follow specific steps in a specific order in order to achieve your end goal.
- Computers influence human behavior by allowing us new forms of communication and interactive exchanges; whether it be information or just means of communication. Computers also change the way we relate to the world as more and more abilities and information are accessible in a way never before seen.
