Assemble the breadboard circuit and implement this system introduced within the video to create an adaptable evening gentle and detailed in Chapter 2 (pp.35-39) of your textbook.
Lab 3b:
Process:
This week’s lab will simulate the espresso maker heater performance we noticed in Week 1. The distinction in our program and the precise espresso maker is that as an alternative of turning on a heating component, our program will blink an LED.
Design a circuit and Arduino program that expands the ideas defined in Chapter three ( pp. 52- 59) of your textbook and accomplishes the next:
Blinks an LED when the temperature of a temperature sensor is at or under room temperature for greater than 5 seconds
If the temperature exceeds room temperature for greater than 5 seconds, the LED will flip off.
Embody a video of your circuit in operation and any pc screenshots throughout its operation. Please embrace your Grantham ID quantity within the video to indicate your work.
Ship your code file (.ino) of the lab accomplished and operational as nicely for credit score.
Assessment/Dialogue:
Clarify the method you used on this lab to reach on the remaining design of each the hardware portion and the software program portion to attain the design goals.
Examine how a temperature sensor such because the TMP36 used on this lab works. In different phrases, describe the connection between the values learn from this system and the way it correlates to temperature.
Why is that this system additionally known as a “transducer”? What are another frequent sorts of transducers that you’re conversant in?
Measure the output voltage of the TMP36 on the level at which this system turns the LED off with a digital multi-meter. Take an image of the digital multi-meter to confirm that correct measurement has been made.
How does the earlier measurement evaluate to the knowledge discovered within the following plot of output voltage versus temperature?
Reply these questions and submit with code and screenshots of your circuit and program.
