Bought One New Arduino Mega 2560 - R3, Most Amazing Arduino Board

by realfinetime  |  in Arduino Mega at  02:38

Arduino Mega 2560 - R3 is an amazing microcontroller board based on ATmega2560. It has 54 Digital input/output pins (Arduino Uno has only 14 Digital input/output pins) of which 14 pins can be used as PWM outputs and 16 Analog inputs (Arduino Uno has only 6 Analog inputs). Apart from these, it has 4 UARTs, a 16 MHz oscillator, a USB connection, a power jack and a reset button.

Arduino Mega is special by it's high performance and amazing look. Portion of Arduino Mega encircled in red in the following figure is exactly similar to Arduino uno. It is designed in such a way that encircled portion will work as Arduino Uno. All the circuits designed using Arduino Uno can be made to work in this portion. Apart from all these, it's most amazing feature is 256k flash memory where Arduino Uno has only 32k of flash memory.

Comparison between Arduino Uno and Arduino Mega.


  1. Thanks for making the effort to describe the terminlogy to the beginners!

  2. The contents of the RAM do get erased when the Arduino is reset. That includes the variables and registers, including the instruction pointer. How to Clear Arduino Memory?

  3. Thanks for sharing the crack but you need to update this version because here new version Available below;



All the circuits, published in this blog is only after testing and getting proper results in my private lab. When you try these circuits, you should check the supply voltage, polarity of components, presence of childrens nearby and shorts in the circuits. This website will not be responsible for any harm happened to you or your components caused by your carelessness.
