INTRODUCTION
The experiment involved monitoring and displaying lab temperatures using Arduino code to show the measurements on an LCD 1602 screen. To achieve this, a solid grasp of the LCD 1602 hardware was required. Careful wiring and connecting of the Elegoo Mega 2560 to a breadboard, which was in turn linked to the computer,
enabled the system to become programmable using Arduino software. Throughout the experiment, various factors were investigated, with the initial inquiry focusing
on how the temperature changed as the system rotated.
DISCUSSION
1)
Rotate the potentiometer. Are there any changes in the LCD display?
Answer: Rotating the potentiometer caused a significant spike in temperature readings and LCD brightness changes.
2)
By touching the thermistor, can you see the temperature changing? what is the temperature now?
FOR CELSIUS
Answer: Yes the temperature quickly increased to 132.1 degrees Celsius.
CONCLUSION
In this experiment, we focused on monitoring laboratory temperatures using Arduino code to display measurements
on an LCD 1602 screen. A fundamental understanding of the LCD 1602 hardware was essential for the successful setup. This involved meticulous wiring, connecting the Elegoo Mega 2560 to a breadboard, and enabling programmability through Arduino software.
During the course of the experiment, we observed temperature variations, particularly when the system was rotated. These changes indicated the sensitivity of the temperature monitoring system to physical adjustments. Notably, when we rotated the potentiometer, temperature readings spiked dramatically, reaching as high as 127.10 degrees Celsius. This demonstrated the potentiometer's significant impact on temperature values and the importance of calibration.

Furthermore, we encountered inconsistencies in temperature readings when the thermistor was touched. The temperature began to increase at an uneven rate, leading to inaccurate results and a sudden jump of 5 degrees Celsius. Ultimately, this resulted in an overall temperature reading of 132.1 degrees Celsius.
In conclusion, our experiment underscored the importance
of understanding the hardware components and their interactions in temperature monitoring systems. It also highlighted the need for careful calibration and handling of sensitive elements like the potentiometer and thermistor to ensure accurate temperature measurements.
