This sample demonstrates blinking multiple LEDs. The sample also demonstrates the most basic usage of the .NET Core GPIO library. The Blink an LED sample demonstrates a slightly simpler model if you just want to blink a single LED. That sample also demonstrates how to use these samples with Docker containers.
The following code toggles multiple GPIO pins on and off, which powers the LEDs.
int lightTime = 1000;
int dimTime = 200;
int[] pins = new int[] {18, 24, 25};
using GpioController controller = new();
// configure pins
foreach (int pin in pins)
{
controller.OpenPin(pin, PinMode.Output);
controller.Write(pin, 0);
Console.WriteLine($"GPIO pin enabled for use: {pin}");
}
// turn LED on and off
int index = 0;
while (true)
{
int pin = pins[index];
Console.WriteLine($"Light pin {pin} for {lightTime}ms");
controller.Write(pin, PinValue.High);
Thread.Sleep(lightTime);
Console.WriteLine($"Dim pin {pin} for {dimTime}ms");
controller.Write(pin, PinValue.Low);
Thread.Sleep(dimTime);
index++;
if (index >= pins.Length)
{
index = 0;
}
}The following fritzing diagram demonstrates how you should configure your breadboard to match the code above.
