An open-source microcontroller development board is called an Arduino. Simply said, you can read sensors and operate devices like motors and lights using the Arduino. This enables you to upload program to this board that can communicate with real-world objects. With this, you may create technology that responds and responds to the outside environment.
In general, the Arduino is able to communicate with anything that is powered by electricity in some way. And even if it isn’t powered by electricity, you can probably still interface with it using devices that are (like motors and electromagnets).
The Arduino has practically endless potential. Therefore, it is impossible for a single tutorial to teach you all you may possibly need to know. Having said that, I’ve tried my best to provide a brief summary of the essential abilities and information you need to start using your Arduino. This ought to serve as a starting point for more investigation and learning, if nothing else.
Types of Arduinos
- Arduino Uno
The most common version of Arduino is the Arduino Uno. This board is what most people are talking about when they refer to an Arduino. In the next step, there is a more complete rundown of its features.
The NG, Diecimila, and Duemilanove are older iterations of the Arduino Uno product series. It’s crucial to keep in mind that legacy boards lack some of the features included in the Arduino Uno. Some notable variations
Also the Diecimila and NG feature a jumper adjacent to the USB connection and need human selection of either USB or battery power. They both employ ATMEGA168 processors instead of the more potent ATMEGA328 chips.
Before uploading a programme to the Arduino NG, you must hold down the rest button on the board for a short period of time.
- Arduino Mega 2560
The Arduino Mega 2560 is the second most widely used model in the family of Arduino boards. The Arduino Mega is comparable to the bigger brother of the Arduino Uno. It features memory of 256 KB (8 times more than the Uno). Additionally, it included 54 input and output pins, 14 of which may be used for PWM and 16 of which are analogue pins. However, the cost of all the extra capability is a somewhat bigger circuit board. Your project will grow in size while perhaps becoming more effective. For additional information, see the official Arduino Mega 2560 page.
- Arduino Nano
The Arduino Nano is for you if you want to go smaller than the typical Arduino board. This version of the Arduino has been scaled down to a compact footprint that can fit into small locations and is based on a surface mount ATmega328 chip. It is extremely simple to prototype with because it can be plugged right onto a breadboard.
- Arduino LilyPad
The LilyPad was created for use in e-textile and wearable applications. It is meant to be linked to other sewable components using conductive thread and to be stitched to cloth. An exclusive FTDI-USB TTL serial programming cable is needed for this board. The Arduino LilyPad page is a good place to start if you want additional details.
Key features of the Arduino Uno include
- A design using open source. Being open source provides the benefit of a sizable user base that helps with support and troubleshooting. Finding someone to assist you in debugging your projects is made simple by this.
- A simple USB interface The chip on the board connects directly into your USB port and shows up as a virtual serial port on your computer. As a result, you may interact with it just like a serial device. The advantage of this configuration is that serial transmission is a very simple (and tried-and-true) protocol, and USB enables connecting it to contemporary PCs quite simple.
- Power management is quite convenient, and voltage control is built in. Up to 12 volts of external power can be connected, and it will be regulated to 5 and 3.3 volts. It may also be run entirely on power obtained from a USB port.
- 16 MHz clock. It is not the fastest microcontroller available as a result, but it is quick enough for the majority of applications.
- 6 analogue pins and 13 digital pins. You may link your Arduino to external hardware using these pins. These pins are essential for expanding the Arduino’s processing power into the physical world. You are ready to go by simply inserting your gadgets and sensors into the sockets that each of these pins corresponds to.
- ICSP connection for connecting the Arduino directly to a serial device without using the USB port. If your chip becomes corrupt and is unable to communicate with your computer, you will need to use this port to re-bootload it.
- Digital pin 13 has an internal LED attached to it for quick and simple code debugging.
