1. Title: Arduino programming for LCDs and Sensors

2. Introduction

The purpose of this project was to help students improve their Arduino programming skills while working with LCDs, Sensors, and Actuators. The programming tasks to control these devices were based on different functions such using a LCD to display the temperature and humidity from ultrasonic and remote sensors.  Additionally students were task to use motors as actuators. By the end of this project, students gained an ability to program the Arduino R3 microcontroller to control LCDs, Sensors and Actuators.


3. Materials and Methods

The step-to-step procedure on how to program the Arduino R3 microcontroller for LCDs, Sensors, and Actuators was provided by Dr. Li on his webpage and can be found here.

The lab procedure consisted on following and understanding the programming examples on Dr. Li’s tutorials. This allowed students to understand the functionality of the mentioned devices and edit previous code to perform different tasks.

Project 4 consisted on completing tasks 1-9 and reporting the results.

4. Results

Figure 1: Task 1 – Display “Hello World” starting from the second rectangle on the same line.

Movie 1: Task 2 – Count to 5 then reset to 0.

Movie 2: Task 3 – Scrolling Text

Movie 3: Task 4 – Thermistor room temperature reading

Figure 3: Task 5 – DHT11 measuring temperature and humidity

Figure 4: Task 6 – IC temperature sensor (TMP36)

Movie 4: Task 7 – IR Receiver Module

Movie 5: Task 8 – Barebone ATmega328p

5. Discussion

Tasks 1 - 8 were performed and executed successfully. Task 9 was unsuccessful, I wasn't able to get my code running. Great project overall, the ability to program Arduino to control different electronic devices will be very useful throughout the students’ engineering careers.
