Ecet 35900 Summer 2014 Laboratory Assignment 6exploring Arduino P

Design and execute an Arduino-based project involving LCD display, temperature sensing, and circuit modifications. The assignment comprises two main phases: first, setting up an LCD to display incrementing text and then integrating a temperature sensor to show real-time temperature data. Follow these steps to complete the assignment successfully:

Phase 1:

1. Connect the circuit to display "LCD text with incrementing number" as demonstrated during the lesson.

2. Upload the sample code, adjusting the potentiometer to optimize LCD contrast.

3. Demonstrate the working setup to the lab instructor.

Phase 2:

1. Using the circuit from Lab #5 Phase 2, integrate it with the Phase 1 circuit to enable displaying temperature readings on the LCD.

2. Combine the two sample sketches into a single program.

3. Convert the analog reading from the temperature sensor into a temperature value in Celsius or Fahrenheit using the map() function.

4. Display the calculated temperature on the LCD.

5. Upload the combined program and verify its functionality.

6. Demonstrate the final setup to the lab instructor.

7. Save the completed program as "LCD".

8. Submit the report form to the lab instructor before leaving.

Paper For Above instruction

The exploration of Arduino microcontrollers provides a hands-on approach to understanding embedded systems and their practical applications. This assignment not only reinforces fundamental circuit connections but also emphasizes programming skills to interface sensors and display outputs effectively. The initial task focuses on constructing a circuit with an LCD to display an incrementing number, which illustrates the capability of the microcontroller to handle output devices and manage display environments. Adjustments to contrast via a potentiometer demonstrate the importance of user interface calibration, making the display visible and readable under various conditions.

Transitioning into the second phase involves integrating sensor data into the display systems, thereby enhancing the functionality of the setup. Incorporating a temperature sensor, such as the TMP36, allows students to comprehend analog-to-digital conversion and the significance of calibration in translating raw sensor readings into meaningful temperature values. Combining this with the existing LCD display illustrates how embedded systems can process environmental data to provide real-time feedback, vital for applications ranging from climate monitoring to home automation.

The process begins with the hardware setup: connecting the temperature sensor to the Arduino, wiring the LCD correctly, and ensuring power stability. After verifying circuit connections, students modify existing sketches to read analog input from the temperature sensor, then use mapping functions to convert these readings into temperature units. Displaying the data on the LCD not only demonstrates successful sensor integration but also enhances students’ understanding of data processing and visualization.

Programming skills are central to this assignment. Combining multiple sketches into a cohesive program requires essential code management, such as managing variable scope, integrating delay functions, and ensuring smooth operation without conflicts. Demonstrating this final project to instructors confirms competence in hardware setup, programming logic, and troubleshooting skills essential for real-world embedded system design.

Overall, this assignment develops a comprehensive understanding of Arduino-based projects, emphasizing end-to-end system integration—from hardware connection, code development, data processing, to user interface considerations. Such experiences are invaluable for students aspiring to work in automation, IoT devices, or any application where embedded systems interact with environmental data and provide real-time feedback to users.
