Controlling multiple LEDs
In the embedded world, controlling a single LED is "Hello World" code, which we learned in first chapter. Now, as we are familiar with the concepts of LED, we can start to control multiple LEDs with Arduino. Here, we will start by making a simple traffic light module.
Simple traffic light controller
As we all know, a traffic light is made up of three LEDs: red, yellow, and green. To make this project, we need red, green, and yellow LEDs, strip wires, and a few 255 Ω resistors.
In the previous chapter, in our "Hello World" program, we connected an LED directly with pin 13. Here, we will connect red, yellow, and green LEDs with pins 9, 10, and 11 respectively. In the case of pin 13, it has an in-built pull up resistor. Pull ...
