Code to control two LEDs connected to pins 13 and 12 of the Arduino Uno. Alternates the LEDs’ states in an inverted way, with intervals of 1 second ON and 0.5 seconds OFF, creating a continuous ...

The traffic light controller logic is implemented using Arduino Uno and programmed in C++ language. The Arduino code includes: Defining pin configurations for LEDs and resistors. Implementing a ...

He has extended a few other I/O pins from the Arduino as well, but he says that the small solder bridges connecting the LEDs can be removed in a pinch, freeing up 8 additional pins with ease.
