RECITATION 3: Sensors by Rannan Elysia

Circuit 

At first, my partner and I planned to make a circuit using a Force Sensitive Resistor (FSR) or “pressure sensor”. Unfortunately, after a few tries, the sensor failed to work properly because of a flaw in the soldering. We had to switch the sensor into a Photoresistor. We followed the said instruction and attached an LED as an output.

We wrote the code with the “if” statement just like how the professor taught us in class. First, we map out the output value from 0-255. If the output value exceeds 50, the LED will light up. The scheme is pretty simple.

The circuit worked perfectly.

QUESTIONS

Q1: I made a circuit with a photoresistor that sense the intensity of the light and used an LED as a form of output. This could be applied in many different ways. One example would be an automatic lamp that would light up when the sensor senses that the surrounding environment is getting dark, and turn off when the sun comes back. This would save up a lot of energy because the lamp would only be used if necessary.

Q2: Because code is our form of speaking with the machine. The machine only understands a series of orders that are precise and organized. The same form can be found in recipe and tutorial because it is like teaching someone who doesn’t know anything. That’s why the order has to be clear.  

Q3: Computer influence human behavior in the sense of accelerating everything. It simplifies our daily tasks and assists in the completion of difficult problems. However, it also negatively influence human interaction. It could help connect people who are miles away but disconnect those who are a meter away.
