Arduino-based Robotic Process Automation (RPA) projects typically involve automating repetitive physical tasks using hardware. For example, you can create a simple robotic arm to press buttons, toggle switches, or perform repetitive movements. Below is a sample program to control a servo-based robotic arm to perform a basic RPA task.

Arduino can be a great platform for building basic AI systems due to its affordability, ease of use, and large community support. While Arduino itself has limited computational power, you can use it in combination with more powerful systems or specific AI-focused add-ons to enable AI-based projects. Here's an overview:

Controlling an **Arduino with JavaScript** can be done using **Node.js** on your computer as an intermediary. By setting up communication between your computer and the Arduino, you can write JavaScript code to interact with the board. Here’s a step-by-step guide to get you started:

Creating an Arduino-based home automation system can be a rewarding project. Below, I will provide a simple example of home automation code using Arduino. This setup will control a few basic appliances like a light, fan, and other devices through a relay module using sensors and a Bluetooth module. 

The ESP32 is a powerful microcontroller with built-in Wi-Fi and Bluetooth capabilities, making it an excellent choice for IoT projects. Let's create a sample project where we build a Wi-Fi-connected weather station using the ESP32, which will display temperature and humidity readings from a DHT22 sensor and send the data to an online dashboard.
