What is Arduino
There are several Arduino boards out there and also a lot of sensors that can take the information from the environment and turn that information into numbers and input for micro-controller. And to connect those sensors to Arduino boards and prototyping your project, you need a breadboard and a bunch of jumper wires.
As we know, It’s based on an open-source electronic platform. It is made up of two parts.
- Hardware
- Software
So let’s inspect the most popular board, which is Arduino Uno. The Uno is the best board to get started with electronics and the Arduino platform. at the center of the board.
We have the brain of the micro-controller, which is AT mega 328P made by Atmel. To power up the board, we have a power jack that can handle 7-12 volts. up here, we have the USB port.
It uses a USB port both for power and to transfer data. As there is a USB to a serial controller and next to the USB, we have the reset button.
Now, here we have 14 digital I/O pins which 6 of which can the PMW output signals. At the bottom left there are 6 analog input pins. Finally, right we have power pins which are 3.3 volts 5 volts GND or ground and voltage in.
To download the IDE software:
- Go to the website
- Click on the software page and download the right version for your OS.
- After downloading and installing, open the Arduino software.
You can change the default settings like the default folder for saving sketches. You can choose the right font.
