ECET 35900 Summer 2014 Laboratory Assignment 6 Exploring

ECET 35900, Summer 2014, Laboratory Assignment #6 Exploring Arduino

Design, implement, and demonstrate a comprehensive Arduino-based project that involves wiring circuits, uploading code, and integrating multiple functionalities. Specifically, you will work through two phases: the first involves displaying incrementing numbers on an LCD, and the second extends this by incorporating temperature sensing and implementing an automatic night light feature. Your tasks include wiring circuits according to provided schematics, modifying and combining Arduino sketches, converting sensor readings into meaningful units, and demonstrating your work to a lab instructor. Additionally, you will prepare and submit a detailed lab report that summarizes your implementation process and findings.

Paper For Above instruction

The purpose of this assignment is to deepen understanding and practical skills in working with Arduino microcontrollers, electronic circuits, and sensor integration. This involves creating interactive projects that demonstrate fundamental principles of embedded systems and sensor data processing. The project is organized into multiple phases, each building on previous work to enhance functionality and complexity, culminating in a comprehensive demonstration and documentation process.

Phase 1: LCD Display with Incrementing Number

Initially, students are required to wire an Arduino circuit to display an incrementing number on an LCD. The wiring diagram typically involves connecting the LCD to the Arduino’s digital pins using a standard 4-bit mode configuration. Once wired correctly, students will upload a sample program that initializes the LCD and continuously updates the display with an incrementing counter. To optimize readability, players may need to adjust the potentiometer connected to the LCD to set the display contrast appropriately.

Following successful setup, students must demonstrate their working circuit and code to a lab instructor, verifying that the LCD accurately displays the count advancing over time. This exercise helps develop skills in circuit wiring, code uploading, and real-time output verification.

Phase 2: Integration of Temperature Sensing and Automated Night Light

Building upon the first phase, students will modify the existing circuit by integrating another subsystem involving temperature sensing and automation. This phase requires students to merge the circuit from the previous LCD display with a temperature sensor (commonly an TMP36 sensor as referenced). The combined circuit involves wiring the temperature sensor to an analog input pin on the Arduino, alongside the existing LCD connections.

The next step involves modifying the Arduino sketch. Students should combine the previous code that displayed numbers with additional code to read the analog input from the temperature sensor, convert this analog reading into a temperature value (either Celsius or Fahrenheit), and display the temperature on the LCD. The conversions often employ the map() function or manual calculations based on sensor specifications.

Furthermore, students are challenged to add logic such that when the temperature crosses a specific threshold, or under certain ambient conditions, an auto night light system activates. This can be accomplished by controlling an output pin connected to a relay or LED that turns on or off depending on the temperature or ambient light measurements taken from the sensor or other inputs.

Once the combined code is written and loaded onto the Arduino, students must verify proper functioning and demonstrate the integrated system to the instructor, showing the sensor readings and automation responses. The final code should be saved with a specific filename, such as “LCD,” indicating its comprehensive functionality.

Additional Requirements and Submission

Throughout all phases, students are required to document their procedures, design choices, and hurdles encountered. After successful demonstrations, the final code should be saved as specified and submitted to the instructor. The entire process contributes to an overarching lab report that consolidates all project phases, captures code snippets, wiring diagrams, and observations, serving as a comprehensive record of the work performed.

Conclusion

This assignment emphasizes practical skills in circuit wiring, sensor integration, code development, and system automation using Arduino. By progressively adding functionality—from basic LCD display to temperature sensing and automated lighting—students gain hands-on experience in embedded systems design. The demonstrations and reports serve as assessments of both technical proficiency and understanding of fundamental concepts in electronics and programming.
