You are all aware of ChatGPT and its power. We tried some experiments and made this ChatGPT Terminal that can incorporate ChatGPT and give you a portable, easy-to-use, complete GPT machine.
You can simply ask a question, seek an answer, or request a snippet of code, using a PS/2 keyboard connected to the ESP32 microcontroller (MCU), and the terminal will assist you in displaying the problem statement on the TFT screen.
The ESP32 will then send the query to ChatGPT, and the output obtained from ChatGPT will be reproduced on the same TFT screen.

You don’t need an elaborate computer for this task. Of course, you need an internet Wi-Fi connection and a secret key to access the ChatGPT API. This is the single-point access key for openai.com; no other login or password is required.
The prototype of ChatGPT Termial is shown in Fig. 1. The components used in the terminal are listed under Bill of Materials in Table 1.
