One of the limitations of the small 8 bit microcontrollers like the Atmel ATMega family adopted by the Arduino board, is the reduced number of I/O ports. Among the main advantages of these ...

In this circuit LM35’s output is connected to the Arduino’s A0 pin, which converts the available output voltage value to a float value of temperature, and then, displays it on the LCD screen. The 10K ...

But they’re more suited for 16-bit microcontrollers which operate at 3.3V levels. His adapter board, which plugs directly into the Mega’s dual-row pin header, makes it easier to control these ...
