Among them, we introduce two ways for Arduino Uno: Arduino UNO + Arduino Ethernet Shield 2 Arduino UNO + PHPoC WiFi/Ethernet Shield Please note: These are affiliate links. There are many ways to connect Arduino to the Internet via Ethernet. The Boeing does it much faster and can carry more people, but flying it is a lot harder than driving a Ford Escort, and you can't fly it on an old-fashioned road. About Arduino with Ethernet Ethernet is the easiest way to connect Arduino to Internet. They're both vehicles, and they can both get you from A to B. It's like comparing a Ford Escort with a Boeing 737. The more powerful SAM3X chip is much harder to get to grips with and program. However when you come to do low-level programming instead if relying on the Arduino API you would find that the ATMega2560 is a much simpler chip to program. The language is, excepting a few esoteric anomalies, largely the same. It's also more forgiving to the novice user than the more complex SAM3X chip.įrom an Arduino programming point of view both boards are pretty much programmed the same. The Mega2560 has less memory and far less processing power, but interfacing with legacy 5V devices is far easier. It can't easily interface with 5V devices though. It has more flexible and more powerful built-in peripherals. It has more memory and far more processing power. The Due can do a lot of things much faster. The Arduino Mega 2560 is still used, because there are many libraries and shields that are compatible with the Arduino Mega 2560. The Arduino Due has more processing power then the M0+. The maximum voltage that the I/O pins can tolerate is 3.3V. When you already know a little about programming and electronics, this is a very good choice. 'yes it is compatible with the Due.' The web says: 'This is on digital pins 11, 12, and 13 on the Duemilanove and pins 50, 51, and 52 on the Mega.' About the DUE 'Unlike other Arduino boards, the Arduino Due board runs at 3.3V. The Arduino Zero or MKRzero or M0 have a M0+ processor at 3.3V and they can be used for all kind of nice projects. Start with an Arduino Uno if you want to learn programming and have fun with leds and buttons. It's always good to have one lying around. My suggestion is to use an Arduino Uno for all kind of testing. The Arduino Mega pins can drive more than 20mA, it can be used to drive 10 leds with 20mA simultaneously, the Arduino Due can't do that. When a 3.3V with SPI is used, you need more hardware. When a 3.3V sensor with I2C is used, you need a I2C level shifter. The Arduino Mega 2560 board is the only board with 10k pullup resistors at SDA and SCL, therefor it has a 5V I2C bus. That is a lot easer with the Arduino Due which runs at 3.3V. Most sensors are 3.3V, and also a SD memory card is 3.3V. Many older shield are not compatible with the Due, but do you really need to use an old shield ? The new Arduino Ethernet Shield 2 is also compatible with the Due. For example the Ethernet Shield V1 version 'R3' can be used with the Due. The 'R3' version boards and shields are compatible with 3.3V and 5V.
