As long as the Arduino board is based on an atmega328, why shouldn't it be? I mean, execution of intructions written into atmega328 memory are based on the clock speed setup, by default 16MHz through external crystal or internal osc. 8MHz, 4MHz and 1MHz setup by the fuses.
The Arduino board and the Atmega328 are not the same thing - the board has many additional components that may affect its reliability. The bare chip can't be used on its own at all so without a bit more context your question "so i can conclude that both are performing same in industry?" can't really be answered.
What aspects of performance are you worried about, speed, reliability, EMC, compliance with safety standards, protection from dirt, ect etc ?
i am worried about accuracy and reliability.now a day i realize one problem with arduino and that is arduino stop working with out any reason.once i start the power arduino working properly after some interval of time it stop working and work randomly.
Excuse my ignorance, what does that device do? is it a power supply with an lcd or a solder station? My first advice is to test the arduino one as standalone device. Is the supply voltage to arduino stable? (no fluctuations?) What i/o pins do you use on it and are you sure it is programmed ok? Thank you.
this is one type of speed datalogger.as per sensor output arduino will count rpm(revolution per minute) and store that rpm with date and time in sdcard.i apply 12v dc to arduino which comes from 7812ic.(power regulator)
