Arduino is basically an open-source electronics platform based on easy-to-use hardware and software. Since it is open-source, one can have access to the files and even modify them for their own work.
Arduino board is a circuit board that has a microcontroller on it which acts as the brain of that board. Apart from microcontrollers, a basic Arduino UNO board has digital and analog pins which take digital/analog input from sensors and give digital output to other components, built-in LEDs, power pins that power other components like basic sensors and basic breadboard circuits, power DC jack and a USB jack.
**TYPES OF ARDUINO SENSORS**
Microcontrollers are integrated chips that are basically tiny computers but are powerful enough to do a lot many tasks like controlling motors and other appliances or they can send some sensor data to the internet cloud, control basic displays and even act as brains of some intermediate level robots.
The Arduino board given in a basic Arduino kit is Arduino UNO which uses a microcontroller ATmega328. There are many more kinds of Arduino boards with other microcontrollers.
**TYPES OF ARDUINO BOARDS**
Arduino also has an official IDE (integrated development environment) named Arduino IDE which has built-in text editor and compiler along with easy-to-use tools to debug and analyze the programs. This can be installed from the official website of Arduino.
Users without an Arduino can use an online simulator like Autodesk Tinker CAD which has a virtual Arduino board that will just function exactly like the actual Arduino board.
**ARDUINO SIMULATION IN TINKERCAD**
Arduino is one of the most widely known microcontroller boards used by students, engineers, and hobbyists to create a multitude of different projects on robotics, home automation, and many others. With Arduino boards, we can control the home activities with the control systems such as motion sensors, outlet control, temperature sensors, blower control, and airflow control.
