If you have ever had to move a project from a basic Arduino Uno to a Mega, you know that the I/O lines on a microprocessor can be precious and few. Therefore, we prefer serial communication, sacrificing potential speed for pin real estate....
3K+ Views A static variable is a special kind of variable; it is allocated memory 'statically'. Its lifetime is the entire run of the program. It is specific to a function, i.e., only the function that defined it can access it. However, it doesn't get destroyed after the function ...
The Arduino UNO board has 14 digital I/O pins (15) (of which 6 provide PWM (Pulse Width Modulation) output. These pins can be configured to work as input digital pins to read logic values (0 or 1) or as digital output pins to drive different modules like LEDs, relays, etc. The pi...
