One such AI Chatbot is Chat GPT, which has gained popularity for its coding capabilities. In this article, we will explore Chat GPT's ability to write Arduino code and control different sensors and devices. We will conduct experiments, test its limits, and discover the strengths and weaknesses of this AI-powered chatbot. So, let's dive into the world of Chat GPT and its coding skills!

What is Chat GPT?

Chat GPT is an AI-powered chatbot that utilizes the OpenAI GPT (Generative Pre-trained Transformer) model to generate human-like responses to user queries. This advanced chatbot is trained on a massive amount of data, allowing it to understand natural language and generate contextually coherent responses. Chat GPT has been programmed to handle various topics, including coding and Arduino development.

Chat GPT's Ability to Write Code

What makes Chat GPT particularly intriguing is its ability to generate code in different programming languages. In this article, we will focus on its capability to write Arduino code, specifically for controlling sensors and devices. With Chat GPT, You can ask it to generate code for various Arduino functionalities, such as blinking LEDs, reading sensor data, and displaying information on LCD screens. It is an exciting tool that can simplify the coding process for hobbyists, beginners, and even experienced developers.

Experiment: Writing Arduino Code with Chat GPT

To explore Chat GPT's coding skills, we conducted an experiment using an Arduino Nano, various sensors, and the Chat GPT chatbot. Our goal was to test whether Chat GPT could generate code to control these sensors and devices effectively. We started with a simple task: blinking the Arduino Nano's built-in LED.

Controlling Sensors with Chat GPT

Before diving into complex tasks, we wanted to see if Chat GPT could handle basic Arduino functionalities. We asked it, "Can you write Arduino code to blink the built-in LED?" Chat GPT Promptly Generated the appropriate code, which included setting Pin modes, controlling the LEDs, and introducing a delay for the blinking effect. We uploaded the code to the Arduino Nano and observed that the LED successfully blinked at the desired frequency.

Adjusting the Blink Frequency

Next, we wanted to test whether Chat GPT could adjust the blink frequency. We asked it to modify the code to make the LED flash at 10 Hertz. Chat GPT quickly generated the updated code, which incorporated the necessary delay to achieve the desired frequency. We uploaded the new code and confirmed that the LED blinked at the specified rate.

Introducing Duty Cycle

To further evaluate Chat GPT's capabilities, we asked it to modify the code to implement a duty cycle. We requested a 10% duty cycle, where the LED would be on for 10 milliseconds and off for 90 milliseconds. However, Chat GPT struggled to generate the correct code for this specific requirement. It consistently provided code that resulted in a blink rate of 20 Hertz instead of the desired 10 Hertz. This highlighted a limitation in Chat GPT's ability to handle certain complex concepts related to frequency and duty cycle.

Working with ACS 712 Current Sensor

Moving on from basic functionalities, we decided to test Chat GPT's ability to work with external sensors. We selected the ACS 712 current sensor, capable of measuring up to 30 amps. This sensor provides an analog output voltage, which requires mathematical conversion to obtain current values.

Converting Analog Output Voltage to Current

We asked Chat GPT to generate Arduino code to measure current using the ACS 712 sensor. Although the provided code successfully converted the analog input value to voltage and then divided it by the sensor's sensitivity, we noticed some inaccuracies in the readings. This discrepancy could be attributed to external factors such as variations in the Arduino's supply voltage. Despite this minor flaw, Chat GPT demonstrated the potential to Create code for complex functionalities involving external sensors.

Calibration and Sensitivity

A vital aspect of using the ACS 712 current sensor is calibrating it according to the specific variant of the sensor. Different versions with varying amperage ratings require different sensitivity values. Chat GPT acknowledged this requirement and provided an explanation of the sensitivity value in the generated code. However, it did not provide explicit instructions on calibrating the sensor for accurate readings. Therefore, it is essential for users to understand the necessary calibration steps for their specific sensor variant.

Ultrasonic Distance Sensor with HC-SR04

Continuing our exploration, we decided to experiment with the HC-SR04 ultrasonic distance sensor. This popular sensor uses ultrasonic waves to measure the distance between the sensor and nearby objects. We tasked Chat GPT with generating Arduino code to measure distance using the HC-SR04 sensor and display the results on a 1602 LCD screen.

Understanding the Wiring

Chat GPT provided Relevant code to interface the HC-SR04 sensor with the Arduino Nano. However, it did not include a wiring Diagram, which could be challenging for beginners. We had to refer to our knowledge of sensor wiring and the provided code's pin definitions to connect the sensor correctly. Once the wiring was complete, we uploaded the code to the Arduino Nano and proceeded with testing.

Exploring the Code and Accuracy

To our surprise, Chat GPT's generated code for the HC-SR04 sensor worked flawlessly. The code accurately measured the distance using the time it took for the ultrasonic sound waves to travel and return to the sensor. The distance was then displayed on the 1602 LCD screen. We observed the expected results as we placed objects at different distances from the sensor. However, we discovered minor inaccuracies in the code's explanation of the speed of sound and the calculation of distance. The discrepancy between Chat GPT's explanation and external research highlighted the need for users to independently verify code explanations for accuracy.

Displaying a Countdown Timer on a 1602 LCD

As we delved deeper into Chat GPT's capabilities, we wanted to test its ability to create more elaborate functionalities. We asked Chat GPT to generate Arduino code for displaying a countdown timer on a 1602 LCD screen, commonly used in Arduino projects.

Setting Up the LCD

Chat GPT provided the necessary code to interface the 1602 LCD with the Arduino Nano. The code included pin definitions and specific functions to initialize the LCD and display information. Wiring the LCD accordingly, we uploaded the code and adjusted the contrast using the provided potentiometer. The LCD successfully displayed the countdown timer.

Customizing the Timer

The generated code allowed customization of the countdown duration. However, the code automatically reset the timer once it reached zero. We modified the code to keep the timer at zero after completion, ensuring that it stopped until manually reset. This adjustment provided more control over the countdown timer functionality. Overall, Chat GPT showcased its capability to create complex and customizable code for practical Arduino applications.

Combining Sensors with LCD Display

To expand our experimentation further, we wanted to combine the functionalities of sensor measurement and LCD display. We requested Chat GPT to generate code to measure distance using the HC-SR04 sensor and display it on the 1602 LCD screen.

Measuring Distance and Displaying on LCD

Chat GPT swiftly created the desired code, which merged the ultrasonic distance measurement functionality with the LCD display output. By uploading this code to the Arduino Nano, we were able to observe the real-time distance measurements on the LCD screen. This integration highlighted Chat GPT's capability to handle multiple functionalities simultaneously and create code to control various components.

Testing the Combined Functionality

Upon testing, we found the combined functionality to be effective. The sensor accurately measured distances, and the LCD screen promptly displayed the results. Despite the minor discrepancies in Chat GPT's explanation of the ultrasonic distance calculation, the generated code successfully accomplished the task at HAND. It is worth noting that Chat GPT may have limitations when it comes to explaining complex concepts; however, its ability to generate functional code remains impressive.
