Arduino doesn't exactly use Java, but it has some similarities with Java in terms of syntax. Arduino sketches (programs) are written in a language that's based on C and C++ programming languages. However, the Arduino IDE (Integrated Development Environment) uses a simplified version of these languages to make it easier for beginners to write code.
When you write code for an Arduino, you usually use functions like `setup()` and `loop()` and write statements that are quite similar to what you'd write in C/C++. It may feel similar to Java in some ways, but it's not Java itself.
To summarize:
- **Arduino programming language** is based on **C/C++**, not Java.
- It has some high-level similarities with Java, but itβs not directly related to Java.
Does that help clear things up?
