In this lesson, we will build upon what we’ve already done by adding a servomotor. Remember, my goal was to simulate a railroad crossing by having two flashing LEDs for the signpost, two LEDs for the crossbar that drops down across the road, and the bar itself to lower and…

In this lesson, we will create a simple build using a pushbutton and 4 LEDs. I’ve got an idea for a project that would simulate a railroad crossing with a flashing signal, a buzzer for the siren, and a crossbar that lowers and raises with the press of a button.…
