As explained brieflythe types of memories in Arduino, RAM (or SRAM) memory is the type that get ignored most easily, because there isn’t anywhere you can find out the usage footprint (well i should say not easy to find out). It usually hardly run out so we tend to forget about it...
For beginners, check out the Arduino-compatible Adafruit MetroX Classic Kit - Experimentation Kit for Metro 328 or Arduino-compatible Adafruit Metro 328 Starter Pack. All of these, and more, make Adafruit the best place to shop for all your Arduino & Arduino-compatible needs!

Connect an Arduino to PC with a USB cable. Check out the Serial port used by Arduino in, for example, Device Manager on Windows. It should look likeCOM3. Check out whether the baudrate is set to 9600 bps, or reconfigure it if needed. Burn this program. In preferences of AIDA64, reac...
I liked the description of the EEPROM usage, but I have a few problems with the coding. In the checkLedState(), there is no provision for a value that is not 0 or 1. So if the EEPROM has a 2, the function does not work as planned. ...
